SIN and COS functions have bug ? - papa_robot - 2022-08-16
Hello to the zx basic community. I'm integrating the compiler into my own spectrum bot.
I created a sample sinewave graph
Code:
FOR x = 10 TO 245 STEP 2
PLOT x,100+SIN(2*x*PI/180)*50
NEXT xHowever I see the values jump around 90 deg, see video here

I cannot find any reference in the doc , it is supposed to be sinclair compatible, but in sinclair basic it works ok

nevermind, declared x as float
dim x
