To select the formatting style for math output notation, tap the "Output" button and choose a setting, or use the "output" command.
The "output" command is used to determine which of two styles of mathematical notation will be used when displaying expressions and equations:
The keyword "1d" selects one-dimensional notation. It is the same as the notation used to enter expressions and equations from the command line.
The keyword "2d" selects two-dimensional notation. It approximates standard math notation by depicting fractions in the traditional numerator-above-denominator format, centering expressions, drawing large parentheses, and hiding redundant parentheses. "2d" is the default format.
e.g. / y + z\ / 2(3) \
6 ( i - ----- ) = p | 1 + --------------- |
\ 2 / | /4 + x \ |
| 4 ( ----- - 1 ) |
\ \ 5 / /
Those examples showed some of the program's equation formatting features. The display mimics traditional, two-dimensional mathematical notation in the following ways:
The program also offers a simpler, one-dimensional output mode that matches the style used when entering equations at the command line. To switch to the simpler, one-dimensional output mode, use the "output 1d" command:
> output 1d
* One-dimensional output mode.
Here is the previous variable definition using one-dimensional output and medium detail:
> detail medium
* Detail set to medium.
Solving for x:
x = 5.5 (or 11 / 2, or 5 & 1 / 2)
Since one-dimensional output mode matches the input format, it can be useful for cutting-and-pasting program output back into the program itself.
To switch back to the default, two-dimensional output mode, use the "output 2d" command:
demo> output 2d
* Two-dimensional output mode.
