compute isnan

compute.isnan( arr )

Computes for each array element whether an element is NaN. The function returns an array with length equal to that of the input array. Each output array element is either 0 or 1. A value of 1 means that an element is NaN and 0 means that an element is not NaN.

var out = compute.isnan( [ 2, '3', 5, 4, null ] );
// returns [ 0, 1, 0, 0, 1 ]
