Sin returns the sine of the given angle(Radians). if 0.224654 is an angle(Radians) then 0.222769070022729 is correct but if 0.224654 is degrees then you need to change it to angle(Radians) and then 0.0039209 is correct...

1 radian = 57.2957795 degrees

So

Code:
Format(Sin(0.224654 / 57.2957795), "0.0000000") will give you 0.0039209
Thanks a lot for the explanation!
