Check whether two values are close to each other, or not:
#Import math Library
import math
#compare the closeness of two values
print(math.isclose(1.233, 1.4566))
print(math.isclose(1.233, 1.233))
print(math.isclose(1.233, 1.24))
print(math.isclose(1.233, 1.233000001))
Try it Yourself » Definition and UsageThe 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.
Tip: It uses the following formula to compare the values: abs(a-b) <= max(rel_tol * max(abs(a), abs(b)), abs_tol)
Syntaxmath.isclose(a, b, rel_tol, abs_tol)
Parameter Values 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 Technical Details Return Value: Abool value. True if the values are close, otherwise False Python Version: 3.5 More Examples Example
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))
