cos 90


for example doesn't return the expected '0', but '-4.37114e-008'. So, if you want to compare results of Cosinus, don't use the compare operator

cos 90
for example doesn't return the expected '0', but '-4.37114e-008'. So, if you want to compare results of Cosinus, don't use the compare operator
(cos 90) == 0
but rather use less than.
(cos 90) < 0.00001
