# Description

The NUMS function is used to determine whether the elements of a dynamic array are numeric or non-numeric strings. The function takes the general form:


If an element is numeric, a numeric string, or an empty string, it evaluates to true, and returns a value of 1 to the corresponding element in a new dynamic array. If the element is a non-numeric string, it evaluates to false, and returns a value of 0.

The NUMS of a numeric element with a decimal point ( . ) evaluates to true; the NUMS of a numeric element with a comma ( , ) or dollar sign ( $ ) evaluates to false.

If dynamic.array evaluates to null, it returns null. If an element of dynamic.array is null, it returns null for that element.

# International Mode

When using the NUMS function in International Mode, the statement will use the Unicode Standard to determine whether an expression is numeric.
