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 :
Python3
# 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:
Python3
# 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
