genType ldexp( genType x, genIType exp );
genDType ldexp( genDType x, genIType exp );


x - Specifies the value to be used as a source of significand.
out exp - Specifies the value to be used as a source of exponent.


 ldexp builds a floating point number from x and the corresponding integral exponent of two in exp , returning:


If this product is too large to be represented in the floating point type, the result is undefined.
