ahltorp, Rather than relying on old school C API for this (
rint), you might want to familiarise yourself with Swift 3’s new
FloatingPointprotocol (SE-0067), which has a bunch of neat-o rounding support, like:
print(2.1.rounded()) // 2.0 print(1.9.rounded()) // 2.0 print(1.5.rounded()) // 2.0 print(-1.5.rounded()) // -2.0 print(1.5.rounded(.towardZero)) // 1.0 print(-1.5.rounded(.towardZero)) // -1.0
@Terry, if you plan to display this string to the user, you should use
NumberFormatterto render number values rather than string interpolation. This will do the right thing regardless of the user’s locale.
Hmmm, then again, if you’re working in eighths of an inch you probably only have one locale you need to work about (-;
