Comment on Java

You wouldn’t need floor/ceil for that. Casting a double to an int is already predictable as the java language spec explicitly says how to do it, so any JVM will do this the exact same way.

The floor/ceil functions are simply primitive math operations and they are meant to be used when doing floating point math.

“predicable” in the sense that people know how it works regardless what language they know.

I guess I mean “no surprise for the reader”, which is more “readability” than “predictability”

  Is there any language that doesn’t just truncate when casting from a float to an int?

    As far as I know, haskell do not allow coresion of float to int without specifying a method (floor, ceil, round, etc)

    Agda seems to do the same: agda.github.io/agda-stdlib/Data.Float.Base.html
