32.17.2.3 Explanation of the COS and COSP Instructions
The COS and COSP instructions are cosine instructions for
trigonometric functions. The COS instruction calculates the cosine
of S1 and stores the result in D1. Enter the number of radians in
S1 to get the result in D1 as a real value between -1.0 and
1.0.
The COS and COSP instructions are always conducted. When using
the COS and COSP instructions, an error will occur if the variables
specified in operands S1 and D1 are not the same type. Designate
the same variable type in all operands S1 and D1.
Refer to the following for specifying a constant.
When operand D1 is a float variable
When 0f (zero and lower case "f") is input, the following values
are interpreted as float values.
When operand D1 is a real variable
When 0r (zero and lower case "r") is input, the following values
are interpreted as real values.
When calculating data in a specified
array
Specify the array using Data [0] or Data [N] (N indicates an
integer variable).
When operands S1 and D1 specify the entire array, an error will
occur even if the specified variables are the same type.
