Decimal Field Pattern limit to 2 decimals only

Question

Hi,
I am want to limit a numeric field to 4 leading digits and only 2 trailing digits, example 1,234.59. I have set this pattern up in the Display pattern: num{z,zz9.99}|num{z,zz9.zz}|num.currency{}.
The problem is if the user enters less than 4 leading digits, s/he can enter more than 2 decimal places. The the field rounds off the value, which I do not want. Example: enters 123.456 = displays 123.46 rather than 123.45.
Any suggestions?
Thanks,
Pam

Pam:
Try setting the field to be Numeric instead of Decimal, and place this in the exit event.
Uncomment the alerts to see the individual results
// multiply by 100 to shift without rounding
temp1 = this.rawValue * 100;
//app.alert("temp1: " + temp1);
// convert to int. to drop remaining decimals
temp2 = parseInt(temp1);
//app.alert("temp2: " + temp2);
// divide by 100 to shift back 2 places
temp3 = temp2 / 100;
//app.alert("temp3: " + temp3);
// return data to field
this.rawValue = temp3;
