Python| numpy ndarray.imag()
借助Numpy ndarray.imag()
方法,我们只需使用ndarray.imag()
方法就可以找到虚数表达式中的虚数值。请记住,虚数的结果数据类型是'float64' 。
Syntax : ndarray.imag()
Return : Array of imaginary values having dtype ‘float64’
示例 #1:
在这个例子中,我们可以看到我们使用ndarray.imag()
方法获取了虚值数组,并且我们还尝试打印这些 imag 值的 dtype。
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([1 + 2j, 2 + 3j])
# applying ndarray.imag() method
geeks = np.imag(gfg)
print(geeks, end ='\n\n')
print(np.imag(geeks).dtype)
输出:
[ 2. 3.]
float64
示例 #2:
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([1 + 2j, 2 + 3j])
gfg = np.sqrt(gfg)
# applying ndarray.imag() method
geeks = np.imag(gfg)
print(geeks, end ='\n\n')
print(np.imag(geeks).dtype)
输出:
[ 0.78615138 0.89597748]
float64
