From c9a5f343bcd33a5cc4405ae298142a3d5fc73d6e Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Thu, 11 May 2000 18:42:27 +0000 Subject: The addition of rint() (by Peter Schneider-Kamp; I forgot to mention that before) in the previous patch has one problem; rint() is not in the C math library on all platforms (e.g. not for VC++). Make it conditional on HAVE_RINT. --- Doc/lib/libmath.tex | 1 + Modules/mathmodule.c | 4 ++++ 2 files changed, 5 insertions(+) diff --git a/Doc/lib/libmath.tex b/Doc/lib/libmath.tex index f4fd2f2..c20fd7f 100644 --- a/Doc/lib/libmath.tex +++ b/Doc/lib/libmath.tex @@ -95,6 +95,7 @@ Return \code{\var{x}**\var{y}}. \begin{funcdesc}{rint}{x, y} Return the integer nearest to \var{x} as a real. +(Only available on platforms where this is in the standard C math library.) \end{funcdesc} \begin{funcdesc}{sin}{x} diff --git a/Modules/mathmodule.c b/Modules/mathmodule.c index e76a32c..1c6b144 100644 --- a/Modules/mathmodule.c +++ b/Modules/mathmodule.c @@ -156,8 +156,10 @@ FUNC2(math_pow, power, math_pow_doc, FUNC2(math_pow, pow, math_pow_doc, "pow(x,y)\n\nReturn x**y.") #endif +#ifdef HAVE_RINT FUNC1(math_rint, rint, math_rint_doc, "rint(x)\n\nReturn the integer nearest to x as a real.") +#endif FUNC1(math_sin, sin, math_sin_doc, "sin(x)\n\nReturn the sine of x.")
