It only takes a minute to sign up. I'd like to restrict user input in a form to a decimal with max two numbers before and 4 after decimal point.

This works just fine and I'm happy with the JS replace method of restricting form input yes I am doing server side validation as well. It seems like I should be able to get the same result with fewer replacements. I think that you are going about this the wrong way. Rather than thinking of what you should remove, you should think of what you should match. This has the problem of matching both fullstops, and numbers 6 digits long.

To amend this you can can use the or operator i. As an alternate to this you can thank that you only include the second half if there is a decimal, and limits the input to two numbers rather than four. Both the above patterns have their pros and cons. Now you want to match these and so you don't want to use replace.

This gives you the option of exec or match. I'd use match due to the simplicity. As you always want the first match and this will always return a match you can simply use something like str. This has the problem that, if you enter This is as you want it to ignore all numbers after the first two and match the decimal and the last four.

To explain this with the demonstration of capture groups you want 12 3. This doesn't capture the 3and so to add this we'll need to capture everything apart from a decimal point.I have created a catalog and added some calculated fields in it.

Thanks Nath. I can see that there is round-up, round-down, round-near and round-zero function. These four functions round the whole number eg. I don't have a round function in there If needs be, you can create a calculation that will round to the correct number of decimal places.

If the round-near doesn't do what you need it to then let me know and I'll work out a formula for you. If that is not what you want, then multiply the number byuse the round function, and divide the result by The original calculation gives the result as 1.

When I multiply the calculation bythen do round-near and then divide bythe value result is still the same 1. Why not just format the field to 2 decimals by using the Toolbar? I need to do the formatting upto two decimal places at the catalog level so that users don't have to worry abt it. You cannot "format" in the catalog.

It is done in the report. If you fix the data in the database to have only two decimals, and then use the report default format of "General", it will show the decimals but not a trailing zero. I do not know if that setting is persistent for all reports I believe it isor for just the "current" report. If Users are creating their own reports, they darn well should know how to format the data themselves.

If the reports are managed reports, the report writer should be formatting anyway. I still don't understand. The user will not have to do anything if you format the field in the report as I described. The user will run the report and the formatting of the field in the report will truncate the data to 2 decimal places.

Granted, if you wanted something other than 2 decimal places this option does not offer you the ability to set the number to something other than 0. In RE: " You can type over the pre-defined formatting rules to get what you want, e. Big Data. Tech Sign In Page.
