Hi, I wrote this code, ran it in the real controller and I was really surprised.
VAR num ii
VAR num AngleStep:=0.1
FOR i FROM 0 TO 360 STEP AngleStep DO
ii:=ii + AngleStep
ENDFOR
result is … ii = 359.918
Hi Martiner.
In Microsoft Visual Basic, with Single precision variables, the result is 360.0128
Probably the FOR statement is implemented in a slightly different way, causing an iteration less, so your error is 0.018; more or less …
But from a theorical point of view your code is very poor. Using floating point numbers always introduce an error. Iterating a sum 3600 times will multiply the error by 3600. Better is:
FOR i FROM 0 TO 3600 DO
ii := i / 10
!
! I think you do something here
!
ENDWHILE
