MantissaExponent

MantissaExponent[x] gives a list containing the mantissa and exponent of a number x.

MantissaExponent[x, b] gives the base-b mantissa and exponent of x.

Example: MantissaExponent[3.4 10^25] .

The mantissa always lies between and or and .

MantissaExponent works with exact as well as approximate numeric quantities.

Example: MantissaExponent[Exp[Pi], 2] .
