How big is a FORTRAN real? On a typical 32-bit machine, a 1-word
(single-precision) floating-point number is "digits 6". "digits 9" would
use a 2-word (double-precision) implementation. This may bias the timing
in favor of FORTRAN.

The trig functions in Ada are pickier than those in other languages; for
a fair comparison, you have to use exactly the same functionality in
both languages.

Also, Text_IO tends to be "heavier" than the IO in other languages.
