Transform integer number

Ideas
1

hello.

i wanted to know if its possible to add this feature under math utilities section.

transform integer number into decimal form.

i mean like this : 2 ➜ 2.000

i wanted to make a formula.that needs the third char.all my numbers are decimal except the first one and this breaks the pattern.

1 , 0.1 , 0.2 , 0.3 , 0.4 , 0.5 ➜ 1.0 , 0.1 , 0.2 , 0.3 , 0.4 , 0.5

thanks.

If all your source values not exist 3 floating points, Try use

$mu(round, your_var, 3)$

otherwise it will round up/down the values.
