it's already defined in include files -> #define HUGE_VAL _huge_dble in math.h ... but any use of this definition don't work
data.u = X * DEG_TO_RAD;
data.v = Y * DEG_TO_RAD;
data = pj_fwd (data, ProjInitRef);
//if (data.u != HUGE_VAL) <- don't work...
if (data.u > 1.0e-100 || data.u < -1.0e-100) //<-instead of huge_val
{
//...
