idiv
Description
Performs integer division of two numbers, placing the quotient back on the stack.
Usage
DividendInt DivisorInt idiv QuotientInt
DividendInt Integer. Number which the interpreter will divide by DivisorInt.
DivisorInt Integer. Number by which the interpreter will divide DividendInt.
QuotientInt Integer. Result of integer division operation.
Comments
On most printers, PAL can perform integer division significantly faster than fixed-point division.
The speed difference becomes important in procedures which the interpreter must execute
repeated.
Integer division discards any fractional portion of the quotient. Therefore, the operation "5 2 idiv"
produces the quotient "2".
