Two Degrees of Spotlight

Did you ever wondered why Apple's Spotlight calculates wrong?
sin(90) =/= 1 but 0,89999 !

Huh? That's... somewhat close, but also totally wrong. Wait, could it be that Spotlight treats the angle as radian, not degrees?
Yes, it does! But luckily there is a small change we can apply: Put a d behind the command like this:

sind(x)
tand(x)
cosd(x)

Now it spits out the expected result.
