Python - cmath.phase() function Last Updated : 28 May, 2020 Comments Improve Suggest changes Like Article Like Report 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 Comment More infoAdvertise with us Next Article Python - cmath.phase() function S SHUBHAMSINGH10 Follow Improve Article Tags : Python Python math-library-functions Python Cmath-library Practice Tags : python Similar Reads Python - cmath.polar() function cMath module contains a number of functions which is used for mathematical operations for complex numbers.
