Number text format dont allow decimals or negatives

[miss_haley]

I have a data card field that I have set to Format: TextFormat.Number

However, when testing this it works perfect for preventing users inputting strings but if they enter negative(-12) or decimal (2.4)

it still work.

For this field I need the input to be whole number only. How may I check and then round the decimals or trim the - symbol? 

I can make warning signs and don't let them press submit. But I would really prefer to limit what can be typed in.

You have to make 'warning signs' as you mentioned.  There's no way to prevent typing a valid number.

You can restrict input values by using another control type like a pre-defined dropdown of numbers or a Slider control.

to check for negative and show error I can type

If(Value(TextInput1.Text) < 0)

Would you know how I can check for the decimal?

I dont know how I can check if "." exist in the textinput

I think you can check for a decimal like this

Mod(your_number_here, 1)<>0

Thanks for reply, I use the IsMatch function and look for decimal as a regex pattern it work.

Yes, that works too.
