Ask HN: Why Ruby doesn’t know how to do maths?
I'm not an expert in maths but the following operation gives a different result in ruby than in any other language or calculator I've tried:
Ruby: (289 / 30 * 30) - (149 / 30 * 30)
150
Rest of the world: (289 / 30 * 30) - (149 / 30 * 30)
140
An explanation is greatly appreciated
