Module Name: src
Committed By: jakllsch
Date: Tue Aug 30 02:58:04 UTC 2011
Modified Files:
src/games/primes: primes.c
Log Message:
No need to cast double to ubig (aka uintmax_t) through int.
This change prevents a modulo by zero in a invocation such as:
primes 18446744073709551000 18446744073709551615
on a LP64 machine.
