Python - cmath.phase() function

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
