The COS function calculates the cosine of an angle expression. The result returned by COS is a decimal value with the same dimensions as the specified expression.
Return Value
DECIMAL
Syntax
COS(angle-expression)
Arguments
A numeric expression that contains an angle value, which is specified in radians.
Examples
Example 11-27 Calculating the Cosine of an Angle in Radians
This example calculates the cosine of an angle of 1
radian. The statements
DECIMALS = 5 SHOW COS(1)
produce the following result.
0.54030
Example 11-28 Calculating the Cosine of an Angle in Degrees
This example calculates the cosine of an angle of 60 degrees. Since 1 degree = 2 * (pi) / 360
radians, 60 degrees is about 60 * 2 * 3.14159 / 360
radians. The statement
SHOW COS(60 * 2 * 3.14159 / 360)
produces the following result.
0.50000
