I got a float array which stores some value thats been calculated by some functions. However, when I retrieve a value from the array, some of the values are -1.#IND, which is a float error or some sort i guess.
So heres my little question, how do I use a if statement to check if the float array contains a -1.#IND value so I can do something with it??
Thanks
if(a != a);
This is only true if a is a NaN.
Oh, and also in cmath there is a isnan() function.
