Cos() returning wrong number...

[blairacuda]

Hello All,

When I run Cos(45) I get .53 in return but plugging it into my calculator returns .7071...etc. I am expecting the .7 number.

I can't find a different function for cosine...

Any help would be great. Thanks in advance.

My calculator gives me what Crystal does:
cos(45) = 0.5253

Cos returns a Number specifying the cosine of an angle given in radians. It takes a right-angle triangle, and returns the length of the side adjacent to the specified angle divided by the length of the hypotenuse.

cos(45 radians) = 0.5253

cos(45 degrees) = 0.7071

Crystal does radians and my calculator defaults to radians. From what I can gather radians is the standard in Trig.

this should get you what you want

convert your degrees to radian like this
45*(crpi/180)

then take your cosine like this

cos(45*crpi/180)

that equals .7071

crpi is the crystal reserved word for pi by the way
