numpy.real_if_close()函数– Python

在这个numpy.real_if_close()函数中，如果复数输入返回一个实数数组，则复数部分接近于零。

Syntax : numpy.real_if_close(arr, tol = 100)

Parameters :
arr : [array_like] Input array.
tol : [float] “Close to zero” is defined as tol. Tolerance in machine epsilons for the complex part of the elements in the array.

Return : [ndarray] If arr is real, the type of arr is used for the output. If arr has complex elements, the returned type is float.

# Python program explaining
# numpy.real_if_close() function
       
# importing numpy as geek 
import numpy as geek 
   
arr = [3.6 + 4e-14j]
tol = 1000
   
gfg = geek.real_if_close(arr, tol)
  
print (gfg)

输出 ：

[3.6]
