It is a pain, but you will need a way to “zero pad” to the right to make sure everything gets carried out to the cent. I typically create a function for this type of thing.
1. Use the floor function to get the whole number part.
2. Concatenate a “.” to the string.
3. Multiply by 100 and use the modulo operator %100 to get the decimal part.
4. Concatenate the decimal part to the string.
