NAME

intdiv - perform integer division in one operation

SYNOPSIS

@load "intdiv"

success = intdiv(numerator, denominator, result)

DESCRIPTION

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

intdiv(numerator , denominator , result )

    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.
