variables: correct minimum float value

FLT_MIN is the minimum normalized positive floating-point value not the minimum negative value a float can contain. This is very different. This fixes the issue with the adjust's hue variable, which has a range of [-180;180]. When the variable was set lower than 0, it was clipped back to zero.
