Assembly: mscorlib (in mscorlib.dll)
The angle, d, must be in radians. Multiply by Math.PI/180 to convert degrees to radians.
Acceptable values of d range from approximately -9223372036854775295 to approximately 9223372036854775295. For values outside this range, the method returns d unchanged rather than throwing an exception.
