Caution for using operand
See the specification of each model for the scope of device’s usage.
Description
S: source value
D: operation result of sine
The source designated by S is radian.
RAD value = degree x π / 180
Find sine 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.
