math.frexp() function

math.frexp() breaks f into a normalized fraction and an integral part of two.

It returns frac and exp satisfying f == frac x 2**exp, with the absolute value of frac in the interval [1/2, 1).

Function type signature
(f: float) => {frac: float, exp: int}
For more information, see Function type signatures.

Parameters

f

(Required) Value to operate on.

Examples

Return the normalize fraction and integral of a value

import "math"

math.frexp(f: 22.0)// {exp: 5, frac: 0.6875}

Use math.frexp in map

import "sampledata"
import "math"

sampledata.float()
    |> map(
        fn: (r) => {
            result = math.frexp(f: r._value)

            return {r with exp: result.exp, frac: result.frac}
        },
    )
