From c383fbf93f691f443eb16761351a6943bc29d3f9 Mon Sep 17 00:00:00 2001 From: naruse Date: Tue, 9 Nov 2010 01:57:49 +0000 Subject: * util.c (ruby_strtod): this code uses FPU's rounding system. But x86's FPU calculates double precision floating-point numbers in 80bit precision, so it fails to round the value. So ensure the value is assigned a variable.
