Arithmetic instructions
POU header In the POU header, all input and output variables are declared that are used for programming this
function.
In this example, the input variable input_value is declared. However, you can write a constant (e.g.
16#45 for 45°) directly at the input contact of the function.
Body In the body, the value 16#45° is assigned to the variable input_value. When the variable start is
set to TRUE, the function is carried out. The result at output d isoutput_value[0] = 0,
output_value[1] = 0, output_value[2] = 7071.
