Notes on operand usage:
Please refer to the function specifications table for each device in
series for the scope of device usage
S: the designated source value. D: the COS value result.
The source designated by S can be given as radians or an angle; this is
decided by flag M1018.
When M1018=Off, the operation is in radians mode, where the radians (RAD)
value is equal to (angle × /180).
When M1018=On, the operation is in the angle mode, where the angular range is
0° ) angle <360° .
When calculation results yield 0, M1020=On.
The COS obtained from the source value designated by S is stored in D.
The following figure displays the relationship between the arc and SIN results:
When X0=On, the COS value of the designated binary floating point number (D1,
D0) in radians will be stored in (D11, D10), with the content consisting of a binary
floating point number.
