Declaration

genTypeldexp(genTypex,genITypeexp);genDTypeldexp(genDTypex,genITypeexp);

Description

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

       significand ⋅ 2 exponent

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

Name

       ldexp - assemble a floating point number from a value and exponent

Parameters

x
           Specifies the value to be used as a source of significand.

       outexp
           Specifies the value to be used as a source of exponent.
