Calculate the absolute value element-wise in Numpy
To calculate the absolute value, we can use two methods, fabs() and absolute(). To return the absolute value element-wise, use the numpy.fabs() method in Python Numpy. This displays the output in float.
To return the absolute value element-wise, you can also use the numpy.absolute() method in Python Numpy. The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
The condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.
Steps
At first, import the required library −
import numpy as np
Create an array −
arr = np.array([76, -81, 91, -100, -120, 150, 200])
Display the arrays −
print("Array...
", arr)Get the type of the arrays −
print("
Our Array type...
", arr.dtype)
Get the dimensions of the Arrays −
print("
Our Array Dimension...
",arr.ndim)Get the shape of the Arrays −
print("
Our Array Shape...
",arr.shape)
To return the absolute value element-wise, use the numpy.fabs() method in Python Numpy. This displays the output in float −
print("
Result...
",np.fabs(arr))To return the absolute value element-wise, use the numpy.absolute() method in Python Numpy −
print("
Result...
",np.absolute(arr))
Example
import numpy as np
# Create an array
arr = np.array([76, -81, 91, -100, -120, 150, 200])
# Display the array
print("Array...
", arr)
# Get the type of the array
print("
Our Array type...
", arr.dtype)
# Get the dimensions of the Array
print("
Our Array Dimension...
",arr.ndim)
# Get the shape of the Array
print("
Our Array Shape...
",arr.shape)
# To return the absolute value element-wise, use the numpy.fabs() method in Python Numpy
# This displays the output in float
print("
Result...
",np.fabs(arr))
# To return the absolute value element-wise, use the numpy.absolute() method in Python Numpy
print("
Result...
",np.absolute(arr))Output
Array... [ 76 -81 91 -100 -120 150 200] Our Array type... int64 Our Array Dimension... 1 Our Array Shape... (7,) Result... [ 76. 81. 91. 100. 120. 150. 200.] Result... [ 76 81 91 100 120 150 200]
