COS

Returns the cosine of expression.

Syntax

COS ( expression )

Example

This example illustrates the COS function:

select cos(45 * pi()/180) 'Cosine of 45 degrees' from sysprogress.syscalctable; COSINE OF 45 DEG ---------------- 0.707106781186548 1 record selected

Notes

COS takes an angle expression and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse.
The expression specifies an angle in radians.
The expression must evaluate to an approximate numeric data type.
To convert degrees to radians, multiply degrees by Pi/180. To convert radians to degrees, multiply radians by 180/Pi.
