[chuck-users] converting from dur to float

In addition to  Rogan's notes;

Dividing any dur by another dur will give you a float so;

second / ms => float thousand;

This is, BTW, a 100% proper; in physics, if I divide a meter into bits that
are a centimetre long then the result will be a 100, a amount without a
unit. If I'd divede the same meter into a hundred(without unit)  bits the
result will be a centimetre (or 0.01 metre) so definitely with a unit.
Duration inherently expresses time and so it will have a unit, unlike
floats.

You may also be interested in .period( dur ), a member function of many
oscillators that sets the period of the wave shape and which is just a
alternative way of expressing the frequency. This can be quite useful for
setting LFO speeds relative to a piece's BPM.

Hope that helps,
Kas.
