Description
S: source value
D: operation result of cosine
The source value designated by S can be set as radian or degree, and this is decided by flag
M1018.
M1018 = OFF, radian mode, RAD value = degree x π / 180
M1018 = ON, degree mode, range: 0° degree < 360°
If the operation result is 0, M1020 = ON
Find cosine value from the source value designated by S, and store in the register that D
designates.
See the figure below for the relation between the radian and the operation result:
Example
When X0 = ON, designate the RAD value of the binary floating-point number (D1, D0) to find
the sine value and stores in (D11, D10). The content is binary floating-point number.
