str2Num doesn’t work as expected

If you are trying to convert a string to a decimal, you might notice that it doesn’t always work. It is very sensitive on the formatting of the string.

Alternatively, you could use the .NET system method to convert the string to a decimal. This handles conversions a little better.

real   decimalValue = System.Convert::ToDecimal(strValue);

Sample job code to test it out the third example.

staticvoid testStringToNumeric(Ar  gs _args)
{
    str     strValue;
    real    realValue;   strValue ="1,123.00";
    print str2num(strValue);//returns 1
    print str2NumOk(strValue);//returns false
try
{
        realValue =System.Convert::ToDecimal(strValue);
        print realValue;
}
catch
{
        print "caught";
}   pause;   }
