[Swift-user] app argument int passed as float

[Michael Wilde]

In at least some recent version of trunk, ints seem to get passed ok, as below.

Now lets see where the difference is.

bri$ cat args.swift
type file;

app (file o) echo(int i)
{
  echo i stdout=@o;
}

file eo<"echo.out">;

eo=echo(123);
bri$ which swift
~/swift/rev/trunk/bin/swift
bri$ swift -version
