code_saturne User's Forum

I was trying to use the "int" symbol as a floor function (as mentioned in the used guide).
I tried to use the function like, for example, "x=int(1.5)" to return "x=1" but I got the following message from the Expression Editor:
In function ‘cs_meg_boundary_function’: expected expression before ‘int’'

What is the mistake?
Is it maybe only usable as an "int" type definition like "int x = 1"? (but in the guide it is listed like a function)

Have you got any working example of the correct usage of "int" as a function?

Thank you in advance.

Hello,

If the user guide mentions int(), this is an error and we need to update this....

The code snippets defined in the GUI formulas are inserted into C code, so if you want to conver a variable x to an integer, you can use the C casting method:
x =(int)1.5;

Best regards,
