- 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!

|
|
- An
emergency update (version 1.4.1) has

workaround for now.
- On
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
display... I've filed a bug report
with Apple, so hopefully they will fix
it in an iOS 7 update soon!
