jax.numpy.frexp
jax.numpy.frexp#
- jax.numpy.frexp(x)[source]#
Decompose the elements of x into mantissa and twos exponent.
LAX-backend implementation of
numpy.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.
- Return type
Tuple[Array,Array]- 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.
