- Version 2.3.1 released on the App Store!
- New and
Improved Features:
- Optimized
the indirect-solution strategies to
avoid useless hypothetical assignments
to variables, such as those that have
been simplified out of equations!
- e.g.
The useless hypothetical value for
"s" after "How many
[feet/(second^2)] is 5.5 Gee?" gets
simplified from "nss/f=5.5(9.8)ss/m"
to "n/f=5.5(9.8)/m"
- Improved
the readability of
natural-language-based answer displays
by removing some extra spacing (added
during the parsing phase) around math
symbols!
- Enabled
Pinch-to-Zoom for the iPad on Help
and "View File" screens!
- Some new
vocabulary for (singular and plural
forms of) "fraction
words" written as numbers:
- inverse
small integers: 3rds, 4ths, 5ths,
6ths, 7ths, 8ths, 9ths, 10ths,
11ths, 12ths, 13ths, 14ths, 15ths,
16ths, 17ths, 18ths, 19ths
- inverse
multiples of 10: 10ths, 20ths,
30ths, 40ths, 50ths, 60ths, 70ths,
80ths, 90ths, 100ths
- inverse
powers of 1,000: 1,000ths,
1,000,000ths, 1,000,000,000ths
(group-separator commas are
optional)
- For
flexibility, these numeric "fraction
words" are understood as expected,
with or without a preceding "/"!
- e.g.
"What percentage of a 3rd is an
8th?"
- e.g.
"How many 16ths is 3/4ths?"
- e.g.
"What's 5 1,000ths[sec] x 225[mph]
measured in inches?"
- Standardized
the usage and translation of "micron"
to the official SI unit
"micrometer"... This can
streamline problem solving by defining
the equivalence of those terms through
a direct, vocabulary-level translation
instead of using an indirect,
equation-level mathematical fact.
- Standardized the translation of "ft"
(and the irregular plural "feet") to the
singular "foot", matching the
singular-form translation convention
used for all other N-dimensional unit
abbreviations and variations (e.g.
"ft2", "feet2", "ft3", "feet3",
etc.)... This fix helps avoid dead
ends (and can streamline problem
solving) by allowing more immediate
symbolic simplification involving units
of feet!
- iPadOS 15+ bug fix for the input line,
Command-mode buttons, or bottom bar
being hidden after showing the iPad
keyboard for dialog box input, but only
if the iPad's Keyboard Shortcuts setting
(Settings --> General
--> Keyboard --> Shortcuts)
was on! This could happen after:
- "Load Algebra" scripted
calculations (or any use of
the "input"
command)
- "Save Transcript" and "Save
Algebra" filename prompts
- Documentation updates and cleanups

- Version 2.3 released on the App Store!
- New and
Improved Features:
- "squared"
(and abbreviations) and "^2" as
non-numeric symbol suffixes, primarily
for 2-dimensional
units:
- e.g.
"The area is 20x12 [ft squared]."
- e.g.
"How many [meters sq] is 26[inches]
by 6.5[ft]?"
- e.g.
"Half of 3,200[ft^2] measured in
[m^2]"
- Vocabulary
words for common macroscopic units
with "2" appended as a shorthand
for "unit squared":
- e.g.
"25[feet2] converts to how many
[meters2]?"
- e.g.
"10[km2] measured in [miles2]"
- e.g.
"How many times 5 x 7[inch2] is 4 x
3[m2]?"
- "cubed"
(and abbreviation "cbd") and "^3" as
non-numeric symbol suffixes, primarily
for 3-dimensional
units:
- e.g.
"30 x 15 x 8 [ft cubed] converted to
[meters cbd]"
- e.g.
"How many times 2[ft^3] is 2[inches]
x 1[m] x 25[ft]?"
- Vocabulary
words for common macroscopic units
with "3" appended as a shorthand
for "unit cubed":
- e.g.
"25[ft3] is 24[in] x 24[in] x how
many [ft]?"
- e.g.
"What percent of 1[m3] is 24 times 4
x 6 x 8[in3]?"
- e.g.
"How much of the volume is 50[cm3]?"
- Knowledgebase
additions formally unifying its
previously-separate concepts of volume
(in bulk) and length (in 3
dimensions):
- e.g.
"What's 1[tbsp] in terms of [in3]?"
- e.g.
"Convert 15[ft] x 30[ft] x 5[ft] to
unit gallons."
- e.g.
"The density of water x 12[ft] x
10[ft] x how many unit inches gives
2[tons]?"
- Knowledgebase
and vocabulary
additions for some 2-dimensional units
of area:
- "acre[s]"
(and abbreviations "ac" and "acs")
- "hectare[s]"
(and abbreviations "ha" and "has")
- "section[s]"
as a synonym for "1 [mile^2]"
- A new
indirect-solution strategy that tries
to avoid situations that might lead to
solving equations for non-linear
variables (such as multi-dimensional
units)! This new strategy allows
AutoMathic to solve most (but not all)
problems involving multi-dimensional
units, despite its fundamental
limitation of still not being able to
solve equations that require taking
square roots, cube roots, etc.
- In-app
examples available in Help
--> Examples
and in File... --> View
File --> eg_MultiDimensionalUnits.htm
- Basic
support for "in" as an abbreviation
for "inch" (and "has" as an abbreviation for "hectares")
when used in the context of a unit:
- e.g.
"5.3[in] measured in [cm]"
- e.g.
"5.3 unit in in unit cm"
- e.g.
"5.3[cm] measured in in" (or
"in terms of", "in unit", etc.)
- e.g.
"44[in/sec] is the
average speed"
- e.g.
"The price is 15[dollars/in]"
- e.g.
"5 x 7[in x in] converted to
[cm^2]"
- e.g.
"The volume is 350[in cubed]"
- New
vocabulary for understanding some
unusual, but valid, musical note terms:
- "C
flat", "Cb", and "C b" as synonyms for
"B natural"
- "F
flat", "Fb", and "F b" as synonyms for
"E natural"
- "E
sharp", "E#", and "E #" as synonyms
for "F natural"
- "B
sharp", "B#", and "B #" as synonyms
for "C natural"
- Added a
height length calculation to the Circle
equation file!
- Added
more "common derivations" to the
BasicProbability equation file!
- Tweaked
some equation files with minor aesthetic
improvements:
- ArithmeticSequence.eqn
- AstronomicalUnits.eqn
- BasicProbability.eqn
- Circle.eqn
- RightTriangle.eqn
- Fixes:
- Documentation
fixes for invalid Unit
Conversion examples using
"converts to":
- WRONG: "
What speed measured
in kph converts to 55 unit
mph?"
- BETTER: "How many unit kph
converts to 55 unit mph?"
- WRONG: "
What speed in
[kph] converts to 55[mph]?"
- BETTER: "How many [kph]
converts to 55[mph]?"

- Version 2.2 released on the App Store!
- New and
Improved Features:
- Natural
language parser enhancements:
- Now
understands more complex "percent
difference" statements (i.e. "_X_
percent more than _Y_"
or "_X_ percent less
than _Y_") where the
second element "Y" can now be
arbitrarily complex, instead of just
a number or very simple noun!
- e.g.
"What percent more than 7[lb/gal]
is the density of water?"
- e.g.
"What's 13% faster than the
speed of sound measured in mph?"
- e.g.
"What percent less than 100
unit meters is 60 unit
yards?"
- e.g.
"Find 7.5 pct under the sum of
3.2 and 2.7 and 5.6."
- Now
understands "a percent" (in any of
its variations) as 1%.
- e.g.
"How much of a percent of
the GDP is ten billion?"
- e.g.
"A pct more than 1,234,567"
- e.g.
"217 is a % less than
what?"
- e.g.
"3.1 is a% of half the
total"
- Bug fix for not treating the "%" sign
like all other math
symbols, causing it to be
misinterpreted or unrecognized when not
followed by a space!
- e.g. "13%/2"
- e.g. "What%=3/5?"
- Bug
fixes for some incorrect parsing
of the word "of", often
following a user-entered fraction
with a numeric denominator!

|
2013-09-28
|
|
|
- An
emergency update (version 1.4.1) has

iPads running iOS 7, long scrolling
lists (e.g. file lists) still don't
display properly, but they still work if
you can read through the corrupt

with Apple, so hopefully they will fix
it in an iOS 7 update soon!
