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

(Ýis 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 +.
