jax.numpy.frexp¶

jax.numpy.frexp(x)[source]¶

Decompose the elements of x into mantissa and twos exponent.

LAX-backend implementation of frexp().

Original docstring below.

Returns (mantissa, exponent), where x = mantissa * 2**exponent`. The mantissa lies in the open interval(-1, 1), while the twos exponent is a signed integer.

Parameters

x (array_like) – Array of numbers to be decomposed.

Returns

mantissa (ndarray) – Floating values between -1 and 1. This is a scalar if x is a scalar.
exponent (ndarray) – Integer exponents of 2. This is a scalar if x is a scalar.
