Section 8. Processing and Math Instructions

Remarks

The following table illustrates how Result is determined:

If expression1 is And expression2 is The result is

True True True

True False False

False True True

False False True

False Null True

The IMP operator performs a bitwise comparison of identically positioned bits

in two numeric expressions and sets the corresponding bit in result according

to the following table:

If bit in expression1 is And bit in expression2 is The result is

0 0 1

0 1 1

1 0 0

1 1 1

Int, Fix

Return the integer portion of a number.

Syntax

x = Int (source)

x = Fix (source)

Remarks

The source can be any valid numeric expression. Both Int and Fix remove the

fractional part of source and return the resulting integer value.

If the numeric expression results in a Not-a-Number, Int and Fix return a Not-

a-Number.

The difference between Int and Fix is that if number is negative, Int returns

the first negative integer less than or equal to number, whereas Fix returns the

first negative integer greater than or equal to number. For example, Int

converts -8.4 to -9, and Fix converts -8.4 to -8.

Int and Fix Function Example

This example illustrates the use of Int and Fix.
