I have to check the lower & upper limits for a float variable.
Problem is that when i check the lower limit of float with 'FLT_MIN' it just checks it with '0.0', which seems right since in 'float.h' it is defined as :

#define FLT_MIN 1.175494351e-38F /* min positive value */

But i want to check it for the minimum negative value for float ??

Is it possible..:confused:? If yes :-D ....can you please explain with a few lines of code ?

:-D THANKS IN ADVANCE :)

FLT_MIN is the minimum positive value. If you want minimum negative value then use -FLT_MAX.
