cmath Methods : Compare the closeness of two complex values
The cmath.isclose()
method checks whether two
complex values are close, or not. This method returns a Boolean value: True
if the values are close, otherwise False
.
This method uses a relative tolerance, or an absolute tolerance, to see if the values are close.
Parameter | Description |
---|---|
a | Required. The first value to check for closeness |
b | Required. The second value to check for closeness |
rel_tol = value | Optional. The relative tolerance. It is the maximum allowed difference between value a and b. Default value is 1e-09 |
abs_tol = value | Optional. The minimum absolute tolerance. It is used to compare values near 0. The value must be at least 0 |
Return Value: | A bool value. True if the values are close, otherwise False |
---|---|
Python Version: | 3.5 |
Compare the closeness of two complex values where absolute tolerance is defined:
#Import cmath Library
import cmath
#compare the closeness of two
complex values using absolute tolerance
print(cmath.isclose(10+5j, 10+5j,
abs_tol=0.005))
print(cmath.isclose(10+5j, 10.01+5j, abs_tol=0.005))
