How to put validation on decimal precision ?

You can use regexmatch() to acheive this

I would do an expression rule that receives a text and do the checks making use of the following supporting functions:

split() - to find separate the arrays before and after the decimal point

lenght() to see the number of numbers on each of the arrays returned from split

Then I would stored as a text to make sure you dont lose precision

Hi, Thank you for you response - I am using split function and comparing the length but not sure why appian converts the value into exponential form . How do i retain the original value ?

regexmatch("^-?\d{0,13}(\.\d{0,9})?$",ri!number) 

I created this regex expression but it works untill Appian converts value into exponential form . Is this expected behavior ? or Am i doing something wrong?

I dont know what you are doing as you are only showing the test inputs....

anyways, if you have it with the exponential it means that at some point you are not working with a string, but rather with a number. As well, if the test inputs you might want to write "12.12312" instead of the number directly

Hi Anu,

We have a function called fixed(). This function has number and decimals(The number of digits after the decimal that will be maintained. 2 by default) fields.

refer documentation here: fixed function

example: fixed(7.36819, 3) returns 7.368

 In your case : fixed(ri!enteredValue, 9)

Hi,

I am facing the similar issue now. Did you manage to solve this problem? Appreciate your response.

Thanks,

Arun

You can store this value into a seperate variable by using text function and do the validation on that variable.

I tried fixed but not working.
