[Swift-user] floor(), ceil() and round() issues with v0.8.0

[Tim Armstrong]

Hi Tim,
  The return type of those functions changed to float in 0.8.0 as part of a
bigger effort to standardise the Swift library.  We tried to keep things
backwards compatible as much as possible but unfortunately there wasn't a
way to do that in this case.

You can get the same effect with toInt(floor(7.8))
