isclose
(a, b, rtol=1e05, atol=None, equal_nan=False, **kwargs)[source]¶ Return a boolean array where two arrays are elementwise equal within a tolerance.
 Parameters
 a, barray_like or
Quantity
Input values or arrays to compare
 rtolarray_like or dimensionless
Quantity
The relative tolerance for the comparison, which defaults to
1e5
. Ifrtol
is aQuantity
, then it must be dimensionless. atolnumber or
Quantity
The absolute tolerance for the comparison. The units (or lack thereof) of
a
,b
, andatol
must be consistent with each other. IfNone
,atol
defaults to zero in the appropriate units. equal_nan
bool
Whether to compare NaN’s as equal. If
True
, NaNs ina
will be considered equal to NaN’s inb
.
 a, barray_like or
 Raises
 UnitsError
If the dimensions of
a

, oratol
are incompatible, or ifrtol
is not dimensionless.
