==== Nasty roundoff problems with textranslate step and scroll. ==== | |||
The textranslate function is delightful for 3D animation | |||
of mechanical drum-type displays as on old-fashioned | |||
odometers and Hobbs meters. | |||
It is not, however, a convenient way to implement digital | |||
readouts. It works OK for integers, but the code in | |||
apply_mod() suffers from deep-seated numerical instability | |||
when dealing with decimal fractions, such as the ".1" in | |||
122.1 MHz, particularly when the scroll-value is zero. | |||
* One workaround is to stick to integers, e.g. integer | |||
kHz rather than fractional MHz. | |||
* Another workaround is to always employ a small positive | |||
scroll value. A patch to make a positive scroll value | |||
the ''default'' has been offered but not yet incorporated. | |||
What we really need is a whole new support routine for dealing | |||
with 3D digital displays, something at least as nice as the | |||
support for 2D instruments. | |||
