# cupy.allclose¶

cupy.allclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False)[source]

Returns True if two arrays are element-wise equal within a tolerance.

Two values in a and b are considiered equal when the following equation is satisfied.

$|a - b| \le \mathrm{atol} + \mathrm{rtol} |b|$
Parameters: a (cupy.ndarray) – Input array to compare. b (cupy.ndarray) – Input array to compare. rtol (float) – The relative tolerance. atol (float) – The absolute tolerance. equal_nan (bool) – If True, NaN’s in a will be considered equal to NaN’s in b. if True, two arrays are element-wise equal within a tolerance. bool
