Map and Table Calculation

- operator

The subtraction operator subtracts two values, i.e. a - b.

Syntax

a - b

Input

a is a value
Domain type: any Value domain
b is a value
Domain type: any Value domain

Output

- returns: a real value
Domain: system domain Value

Note:

When one of the operands is undefined, or when both operands are undefined, the output will also be undefined.

Tip:

When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.

Usable in

MapCalc, TabCalc, Simple calculators

Examples

Pocket line calculator examples:

? 10-2

returns 8

? 2^3-4

returns 4.000

MapCalc example:

OutMap = InMapA - InMapB
