I use ANSI C89 (not C++), and I want to generate NaN, -Infinity and +Infinity. 开发者_StackOverflow社区
I have a moderately large piece (a few thousand lines) of Python/Numpy/Scipy code that is throwing up NaNs with certain inputs. I\'ve looked for, and found, some of the usual suspects (log(0) and the
I unfortunately cant use expressions like Long.Nan as the string is actually a return value from a different C module. Is there a string开发者_开发问答 I can pass to parseLong() to return an NaN ?Ther
I am making a simple dice roller, which seems like a good first project to me, and may help others learn javascript as well, and when you roll a die (with a button), it is supposed to add to the total
To debug my a开发者_StackOverflow社区pplication (fortran 90) I want to turn all NaNs to signalling NaN.
Assume you have a function like F = lambda x: sin(x)/x Evaluating F(0.0) would result in a divide by zero warning, and would not give the expected result of 1.0. Is it possible to write another fu
I want to know what makes a float number nan in c++. I am using a large dataset and it is really hard to trace. I want to know the ways of changing a float number to nan to reduce bug possibilities.
Is it possible to set an element of an array to NaN in Python? Additionally, i开发者_C百科s it possible to set a variable to +/- infinity? If so, is there any function to check whether a number is in
Is there an isnan() function? PS.: I\'m in MinGW (if that makes a difference). I had this solved by using isnan() from <math.h>, which doesn\'t exist in <cmath>开发者_开发知识库, which I
To find the cause of floating point variables beeing set to NaN in my C++ program I enabled floating point exceptions like this:
