I am pretty formatting a floating point number but want it to appear as an integer if there is no relevant floating point number.
I.e.
- 1.20 -> 1.2x
- 1.78 -> 1.78x
- 0.80 -> 0.8x
- 2.00 -> 2x
I can achieve this with a bit of regex but wondering if there is a sprintf
-only way of doing this?
I am doing it rather lazily in ruby like so:
("%0.2fx" % (factor / 100.0)).gsub(/\.?0+x$/,'x')
