Rust cast to f64

WebbCasting from an f32 to an f64 is perfect and lossless Casting from an f64 to an f32 will produce the closest possible value (rounding strategy unspecified) NOTE: currently this will cause Undefined Behavior if the value is finite but larger or smaller than the largest or smallest finite value representable by f32. This is a bug and will be fixed. Webb6 apr. 2015 · Rustc panics on division of f64 and i32 #24138. Closed. dmner opened this issue on Apr 6, 2015 · 5 comments · Fixed by #25344.
