Better use SI :-)
Anyway, multiply the fractional part with a large power of two (e.g.
1024).
The resulting number is the upper part of your fraction, and 1024 below.
Then use the normal common denomitor way to simplify it to aa sane number.
- number: 3.25
- frac(3.25) = 0.25
- 0.25*1024=256
So 3 256/1024
