How do I keep the 0 decimals (trailing zeros) in a float?

I am aware that I can use the following code to restrict my number to two decimal places (eg 99.99):

round(float(Value_Inputs.Text)*100)/100

However, numbers with zeros after the decimal do not display as expected, for example:

12.00 displays as 12

12.50 displays as 12.5

SO, how do I go about keeping the trailing zeros?

Thanks

EDIT: I saw a solution here: https://www.construct.net/en/forum/construct-2/how-do-i-18/decimals-zeros-shown-50800 but I tried it and it just seems to make everything round to .00 ...eg 12.5 becomes 12.00 which is not what I want.

it definitely gets a little tricky to do it with events... but it is quite easy with javascript:

toFixed does the rounding and will keep the number of decimal places in the round brackets.
