conversion of degrees

[psykedelik]

is it posible to convert double values into degrees?i have this project in c++ that derive a formula and requires conversion into degrees/angle.

ex. of sol in trigonometry

cos C=a*a+b*b-c*c /2ab

hope you can help me.tanx

No. A double is a storage type. A degree is a unit of measure.

You can convert numbers using one unit of measure to another unit of measure.


After looking at your question a few times now, I think I understand it. You want to convert radians to degrees, right?
degrees = C * 180 / 3.1415926;

Define pi to as many digits as you like.

k, tanx for the advice.
