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.
Access: …Ý (Ý is the right-shift of the -key).
Input: Numeric value
Output: Numeric value ready for a unit attachment
« » (Program delimiters)
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.
Access: …å (å is the right-shift of the +key).
Input: None
Output: A pair of program delimiters
< (Less than)
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 (–2 is less than –1).
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 +.
Access: …Ç (Ç is the right-shift of the Xkey above the 8).
