`numpy.lib._nanfunctions_impl:_replace_nan`

source: build-install/usr/lib/python3.14/site-packages/numpy/lib/_nanfunctions_impl.py :70

Signature

def _replace_nan ( a , val )

Summary

If a is of inexact type, make a copy of a, replace NaNs with the val value, and return the copy together with a boolean mask marking the locations where NaNs were present. If a is not of inexact type, do nothing and return a together with a mask of None.

Extended Summary

Note that scalars will end up as array scalars, which is important for using the result as the value of the out argument in some operations.

Parameters

a : array-like: Input array.
val : float: NaN values are set to val before doing the operation.

Returns

y : ndarray: If a is of inexact type, return a copy of a with the NaNs replaced by the fill value, otherwise return a.
: mask: {bool, None}: If a is of inexact type, return a boolean mask marking locations of NaNs, otherwise return None.
