Python – cmath.phase()函数
cMath 模块包含许多用于复数数学运算的函数。 cmath.phase()函数用于获取复数的相位。此函数中传递的值可以是int、float和复数。
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.
下面的例子说明了上述函数的使用:
示例 #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)
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)
输出:
0.0
示例 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)
输出:
1.3258176636680326
