[Gambas-user] using Sin() to produce a specific range of values

Again my thick skull prevents me from figuring this out, even with
I need to use the Sin() function to calculate an output range from an
input range. The advantage of Sin() is that it's not linear; it makes a
nice smooth curve of values sort of like a sound wave in an audio editor.
I need to produce an output range of values from 0 to 255, then back
from 255 to 0. A linear example would be:
0, 31, 63, 95, 127, 159, 191, 223, 255, 223, 191, 159, 127, 95, 63, 31, 0
Sin()'s output should start at 0, peak at 255, then go back down to 0.
The input range I can control so whatever is easiest or most efficient
will work fine.
The Greek symbols in the official math references are a bit much for
what should be a simple equation rather than a math lesson. ;) Any help
is appreciated as always.
