NAME

mod-div-specs - provide infix div / mod according to spec

SYNOPSIS

use mod-div-specs;

say 42 div 7;    # 6
say 42.2 div 7;  # Cannot resolve caller infix:<div>(Rat:D, Int:D)

say 42 mod 9;    # 6
say 42.2 mod 9;  # Cannot resolve caller infix:<mod>(Rat:D, Int:D)

DESCRIPTION

The mod-div-specs exports a version of the infix div and infix mod operators that match the description in the old design documents of what is now the Raku Programming Language.

In this design, div and mod (as integer optimized versions of / and %) would only accept integer arguments. Several changes in the Rakudo implementation of Raku added automatic coercions at various times, with sometimes unexpected results.

This distribution attempts to create a clear interface, with immediate execution errors if the interface was not adhered to.
