Description
S: source value (binary floating-point number)
D: operation result of arctangent
ATAN value = tan

See the figure below for the relation between the input value and the operation result:
Example
When X0 = ON, designate the binary floating-point number (D1, D0) to find the arctangent value
and stores in (D11, D10). The content is binary floating-point number.
