History
ColdFusion MX: Changed behavior: if the mask format cannot correctly mask a number, this
function returns the number unchanged. (It does not truncate the number nor throw an error.)
(If no mask is selected, ColdFusion MX rounds the decimal part as ColdFusion 5 does. For
example, it rounds 34.567 to 35.)
