Integer function allows non-integers

[JamoCA]

I noticed there was an "integer" udf in the securityutil CFC. I couldn't find any reference to it being used by the library, but if it is please consider using the following condition to determine whether the value is an integer or not... otherwise post-validation errors could occur when passing values that exceed allowable integer limits.

function isInteger(num){
    return isSimpleValue(num) AND refind("^-?\d+$", num) AND VAL(num) LTE 2147483647 AND VAL(num) GTE -2147483648;
}
