# [NAME](#NAME)

intdiv - perform integer division in one operation

# [SYNOPSIS](#SYNOPSIS)

@load "intdiv"

success = intdiv(numerator, denominator, result)

# [DESCRIPTION](#DESCRIPTION)

The *intdiv* extension provides a single function that performs integer division, similar to the standard C div() function.

[**intdiv(numerator, denominator, result)**](#intdiv%28)

First, truncate *numerator* and *denominator* towards zero, creating integer values. Clear the *result* array, and then set **result\["quotient"]** to the result of *numerator / denominator*, truncated towards zero to an integer, and set **result\["remainder"]** to the result of *numerator % denominator*, truncated towards zero to an integer. Attempting division by zero causes a fatal error. The function returns zero upon success, and -1 upon error.

This function is useful primarily with GMP arbitrary length integers; it avoids creating MPFR arbitrary precision floating-point values.
