rounding problems

[Alan Jeffrey]

now...  At the time I needed a language with good scripting facilities, and
TeX's macro language looked quite reasonable.  And it means it runs on any
TeX-aware site (blah blah usual advertizing stuff here).

That's one of TeX's features that make me sometimes wonder whether TeX
was
really the language of choice for a software like fontinst...
