frexp - dissect floating-point numbers into base 2 exponent and mantissa

Calling Sequence

[f,e]=frexp(x)

Parameters

• x : real vector or matrix
• f : array of real values, usually in the range 0.5 <= abs(f) < 1.
• e : array of integers that satisfy the equation: x = f.*2.^e

Description

This function corresponds to the ANSI C function frexp(). Any zeros in x produce f=0 and e=0.

Examples

[f,e]=frexp([1,%pi,-3,%eps])
