=cos(-180) => -,598460069 ???

[robert_muench]

Hi, I'm wondering about the result for '=cos(-180)' which is shown as  -,598460069  but should be -1

 

Any idea what's going on?

@robert_muench Alfred's calculator is based on GCMathParser which works in radians. If you type cos(-180) into google, you'll see the same.

 

Cheers,

Andrew

Ah, thanks. Didn't had the RAD value in mind... Any link to GCMathParser? The official one seems to be offline. BTW: one can use: =cos(dtor(-180)) to get the correct result.

@robert_muench you're right, it looks like the original page is offline. I'll add a note to update our documentation!
