cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.phase() function is used to get the phase of a complex number. The value passed in this function can be int, float, and complex numbers.
Syntax: cmath.phase(x)
Parameter:This method accepts the following parameters.
- x :This parameter is the number to find the phase of.
Returns:This method returns a float value that represent the phase of a complex number.
Below examples illustrate the use of above function:
Example #1 :
# Python code to implement
# the phase()function
# importing "cmath"
# for mathematical operations
import cmath
# using cmath.phase() method
val = cmath.phase(1)
print(val)
Output:
0.0
Example 2:
# Python code to implement
# the phase()function
# importing "cmath"
# for mathematical operations
import cmath
# using cmath.phase() method
val = cmath.phase(1 + 4j)
print(val)
Output:
1.3258176636680326
