Wrong math

[zarsoft]

PRINT SIN 1
Gives: 0.841461181640625 (wrong)

LET v = 1
PRINT SIN v
Gives: 0.84147098 (right)

They are actually the same value. It's a matter of precission.
SIN 1 is being calculated directly by the compiler in compiling time.
SIN(1) is aprox 0.8414709848078965

The 2nd case is computed in runtime, using the ROM calculator.

I guess this is due to a bug in precision converting from PC to ZX Spectrum 5 bytes format.
Will investigate this and keep you posted.

Thanks
