Returns a value that is the cosine of the specified angle expressed in degrees.
COSD(x)
x is a floating-point value.
COSD(60.0) /* returns 0.5 */
A COSD operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
Description
The COSD function returns a value that is the cosine of the angle x expressed in degrees. The result has the same value type as x such that -1 ≤ COSD(x) ≤ 1.
