Math Methods : Check whether two values are close to each other, or not
The math.isclose() method checks whether two values are close
to each other, or not. Returns True if the values are close, otherwise False.
This method uses a relative or 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 |
Use absolute tolerance:
#Import math Library
import math
#compare the closeness of two
values
print(math.isclose(8.005, 8.450, abs_tol = 0.4))
print(math.isclose(8.005, 8.450, abs_tol = 0.5))
