Template Function TRAP::Math::FrExp(genType, i32&)#

Function Documentation#

template<typename genType>
genType TRAP::Math::FrExp(genType x, i32 &exp)#

Splits x into a floating-point significant in the range [0.5, 1.0) and an integral exponent of two, such that x = significant * exp(2, exponent). This significant is returned by the function and exponent is returned in the parameter exp. For a floating-point value of zero, the significant and exponent are both zero.

Note

For a floating-point value that is at infinity or is not a number, the results are undefined!

Parameters:

  • x – Specifies the value from which significand and exponent are to be extracted.

  • exp – Out specifies the variable into which to place the exponent.

Returns:

See description.
