Exclamation UFD Unsteady Pressure

Hey,
I’ve been told to write the code for UDF unsteady pressure with frequency between 300-500 hz.
The code I am writing is -
#include
"udf.h"
DEFINE _PROFILE (unsteady pressure, thread, position)
{
face tf;
real t = CURRENT TIME;
begin f_loop(f, thread)
F PROFILE(f, thread, position) = 3209122.0 + 5.0*sin(10.*t);
}
end f loop(f,thread)
}

I want to know how can I include frequency in this and this code gives multiple errors when I use pressure value as 3209122. On the other hand when I use value such as 101325 it runs.
Please help me out with the pressure value and frequency.
