! ! ! ! Program Example
Input unit and output results vary depending on the integer number and real
number data.
• Integer Number
It is used within a range of -327.68
°~327.67°. Use an immediate calculation
result (integer number data) as an input, and leave the calculation result in
the integer number register (1 input unit = 0.01
°). The calculation result is
output by multiplying by 100
°.
• Real Number
Use an immediate calculation result (real number data) as an input, and leave
the inverse tangent in the real number register (unit: degree).
