DIV
Synopsis
DIV(numstr1,numstr2)
Arguments
| numstr1 | The dividend. An expression that resolves to a number or numeric string. |
| numstr2 | The divisor. An expression that resolves to a non-zero number or numeric string. |
Description
The DIV function divides the value of numstr1 by numstr2, and returns the integer quotient. It discards the fractional remainder. If a numstr value is a null string or a non-numeric value, DIV parses its value as 0 (zero).
Attempting to divide by zero generates a <DIVIDE> error, ending execution of the function and invoking an error trap handler, if available.
To perform exact division with a fractional quotient, use the division operator (/). To perform modulo division, use the MOD or REM function.
To perform division on the elements of a dynamic array, use the DIVS (divide corresponding elements, generate error on a zero divisor value), DIVSZ (divide corresponding elements, return 0 for a zero divisor value), and MODS (modulo division of corresponding elements) functions The DIVS and DIVSZ functions can return fractional numbers as the result (quotient) of a division operation.
Examples
The following examples use the DIV function to return the integer quotient of a division operation:
PRINT DIV(10,5); ! returns 2
PRINT DIV(10,4); ! returns 2
PRINT DIV(10,3.3); ! returns 3
PRINT DIV(10,3.4); ! returns 2
PRINT DIV(10.2,3.4); ! returns 3
PRINT DIV(10,-3); ! returns -3
PRINT DIV(-10,3); ! returns -3
