The typical program doesn't really use floating-point at all. The issue
is with those few programs/libraries with tons of computation in it.
For Ada, there are some test cases that spend most of the compile time
doing high-precision arithmetic to compute constants for polynomial
approximations to functions.

Now of course, this is mostly because Ada requires calculations of
"static" expressions (subset of compile-time known expressions) to be
performed exactly.

However, if you are doing a lot of inlining and compile numerical code,
I wouldn't be surprised if you'd do a lot of target arithmetic and find
that for some programs the time required is significant.
