Function Sin,Cos in the sysmac studio

[Sannin 0]

Good morning everyone, I'm having difficulty using the "sin" and "cos" functions in sysmac, in particular the results of the functions are not correct, for example if I convert 180° into radians, with the result 3.14159 and then I do "sin", the result is -8.7422777e-08 when it should be 0. Could anyone tell me how to solve the problem? Thank you all

Hi,

The value is almost 0 ( 3.14159  is just approximation of PI) If there's a "." at the end of monitored value that means that this value is not all displayed.

In the end I use the LREAL as a format to get the result even closer to zero. A thousand thanks
