I use Twine 2.0 with Harlowe 1.2.4.
Is there a posibility to format a float? I know that working with floats can be a little tricky (e.g. 3.9999999 instead of 4).
Edit. I forgot to mention I'm on my phone, so I didn't test this.
If you wanted a single decimal place you would multiple/divide by 10, and if you wanted three decimal places you would multiple/divide by 1000, etc...
eg. The following is the integer equivalent of your example.
@greyelf: Thanks a lot! This work for me perfectly
