I would like to compile a simple C90 code utilizing math library: main.c: #include <stdlib.h> #include <stdio.h>
I\'m trying to calculate logab (and get a floating point back, not an integer). I was planning to do this as log(b)/log(a). Mathematically sp开发者_如何转开发eaking, I can use any of the cmath log fun
It seems that cmath for visual studio 2005 does not have erf(x).I am using NIST Statistica开发者_如何学编程l Test Suite for Random and Pseudorandom Number Generators. In cephes.c\'s method, double cep
I have got the following problem: I want to use M_PI defined in math.h. I开发者_如何学Pythonn order to do that, one should define _USE_MATH_DEFINES before including the header.
Hi I\'m trying to do some calculations with long doubles and I am getting INF from sqrt(开发者_如何学编程) function.
I am trying to look for definition and declaration of the functionnanf() - return \'Not a Number function, which is related to the floating point functionality on Linux gcc compiler environment - (gli
I have a fairly complicated function that takes several double values that represent two vectors in 3-space of the form (magnitude, latitude, longitude) where latitude and longitude are in radians, an
This question already has answers here: sqrt from math.h causes linker error "undefined reference to sqrt" only when the argument is not a constant
I assume that abs and fabs are behaving different when using math.h. But when I use just cmath and std::abs, do I ha开发者_运维问答ve to use std::fabs or fabs? Or isn\'t this defined?In C++, it\'s alw
This often returns NAN (\"Not A Number\") depending on input: 开发者_如何转开发 #define PI 3.1415f
