Numpy's signbit(~) method checks whether each element in the array is a negative number.

Parameters

1. x | array_like

The input array.

2. out | Numpy array | optional

Instead of creating and returning a new array, you can store the result in out.

3. where | array_like | optional

A boolean mask where only the values in x corresponding to True in the mask will be considered.

Return value

A Numpy array of booleans where True denotes a negative number, and False for all else.

Examples

Basic usage


        
        
            
                
                
                    np.signbit([3, -4, 5, 0])
