From 5e9b7bacc3731b909ea6341d7158ef6b34e09f2d Mon Sep 17 00:00:00 2001 From: nobu Date: Sun, 12 Jan 2014 00:21:37 +0000 Subject: ruby/util.h: DECIMAL_SIZE_OF_BITS * include/ruby/util.h (DECIMAL_SIZE_OF_BITS): a preprocessor constant macro to approximate decimal representation size of n-bits integer. * iseq.c (register_label): use DECIMAL_SIZE_OF_BITS for better approximation. * ext/bigdecimal/bigdecimal.c (BigMath_s_log): ditto. * common.mk (iseq.o), ext/bigdecimal/depend (bigdecimal.o): add dependency to ruby/util.h for DECIMAL_SIZE_OF_BITS. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44562 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ext/bigdecimal/bigdecimal.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'ext/bigdecimal/bigdecimal.c') diff --git a/ext/bigdecimal/bigdecimal.c b/ext/bigdecimal/bigdecimal.c index c5a3326fb7..16fba2211f 100644 --- a/ext/bigdecimal/bigdecimal.c +++ b/ext/bigdecimal/bigdecimal.c @@ -18,6 +18,7 @@ # define BIGDECIMAL_ENABLE_VPRINT 1 #endif #include "bigdecimal.h" +#include "ruby/util.h" #ifndef BIGDECIMAL_DEBUG # define NDEBUG @@ -2919,7 +2920,7 @@ get_vp_value: RB_GC_GUARD(vn) = SSIZET2NUM(n); expo = VpExponent10(vx); if (expo < 0 || expo >= 3) { - char buf[SIZEOF_VALUE * CHAR_BIT / 3 + 4]; + char buf[DECIMAL_SIZE_OF_BITS(SIZEOF_VALUE * CHAR_BIT) + 4]; snprintf(buf, sizeof(buf), "1E%"PRIdVALUE, -expo); x = BigDecimal_mult2(x, ToValue(VpCreateRbObject(1, buf)), vn); } -- cgit v1.2.3
