NumPy's np.abs(~) method returns a NumPy array with the absolute value applied to each of its values.

NOTE

np.abs(~) is shorthand for np.absolute(~)

Parameter

1. x | array-like

The input array.

2. out | Numpy array | optional

Instead of creating a new array, you can place the computed mean into the array specified by out.

3. where | array of boolean | optional

Values that are flagged as False will be ignored, that is, their original value will be uninitialized. If you specified the out parameter, the behaviour is slightly different - the original value will be kept intact.

Return Value

A NumPy array with the absolute value applied to each of its value.

Examples

To return a NumPy array with absolute values of array x:


        
        
            
                
                
                    x = np.array([-1,2, 3,-4])
np.abs(x)
                
            
            array([1, 2, 3, 4])

Note that the source NumPy array is left intact, that is, x in this example would still have negative values.

NOTE

There is a difference between np.abs and np.fabs() methods. The f in fabs() denotes float, which means that the return type for fabs() is always float. On the other hand, np.abs() returns the same data type as the input array.
