numpy.nextafter(arr1, arr2, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None) : This mathematical function helps user to return next floating-point value after arr1 towards arr2, element-wise.
arr1 : [array_like]Input array, values to find next value of.
arr2 : [array_like]Input array, values in which direction to look for.
out : [ndarray, optional]Output array with same dimensions as Input array, placed with result.
**kwargs : Allows you to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function.
where : [array_like, optional]True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.
Return : next floating-point value of arr1 in the direcrion of arr2.
arr1 : 3 arr2 : 4 Check sign of arr1 : 3.0000000000000004
