__device__ int ilogbf ( float  x  )  Calculates the unbiased integer exponent of the input argument x. Returns: If successful, returns the unbiased exponent of the argument. ilogbf(0) returns INT_MIN. ilogbf(NaN) returns NaN. ilogbf(x) returns INT_MAX if x is or the correct value is greater than INT_MAX. ilogbf(x) return INT_MIN if the correct value is less than INT_MIN. Note: For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-1.
