The calculator handles units by attaching the unit to a numeric value using the underscore symbol. For example, the value of 3 kilometers is shown as 3_km, and is created by entering 3 and then the underscore character, followed by attaching the kilometer unit.

Type: Object
Description: | Program delimiter object: Enters a pair of program delimiter objects. | |
| A program is a set of instructions enclosed by an open program object delimiter and a close | |
| program object delimiter. These can be nested to have a program procedure enclosed within an | |
| outer program object. |

Type: Function
Description: | Less Than Function: Tests whether one object is less than another object. | |
| The function < returns a true test result (1) if the first argument is less than the second argument, | |
| or a false test result (0) otherwise. | |
| If one object is a symbolic (an algebraic or a name), and the other is a number or symbolic or unit | |
| object, < returns a symbolic comparison expression that can be evaluated to return a test result. | |
| For real numbers and binary integers, “less than” means numerically smaller (1 is less than 2). For | |
| real numbers, “less than” also means more negative | |
| For strings, “less than” means alphabetically previous (“ABC” is less than “DEF”; “AAA” is less | |
| than “AAB”; “A” is less than “AA”). In general, characters are ordered according to their | |
| character codes. This means, for example, that “B” is less than “a”, since “B” is character code 66, | |
| and “a” is character code 97. |
|
| For unit objects, the two objects must be dimensionally consistent, and are converted to common | |
| units for comparison. If you use simple temperature units, the calculator assumes the values | |
| represent temperatures and not differences in temperatures. For compound temperature units, the | |
| calculator assumes temperature units represent temperature differences. For more information on | |
| using temperature units with arithmetic functions, refer to the entry for +. | |
