anyhow, i don't like the [expr] because *often* it makes things so less readable (in my opinion [expr $f * 3.14159 / 180] is less readable than the use of [* 3.14159] and [/ 180])
Of course here for speed one ought to use [* 0.017453278], but the reason for the number is less obvious so a comment like 'pi over 180' is in order, which adds nothing to the processing time.
