I have a very old but interesting BASIC graphic program where I've
made some minor changes to operate on a 1920 x 1080 res monitor.

After program is run for some minutes it errors with "Accuracy lost in
Sine/Cosine/Tangent".

How do I stop this error from appearing?

Program is run from SED running RISC OS 5.24 (16-Apr-18) on
Raspberry Pi.
