Does FB 1.0 have a rounding function?

I want to issue a command that sets a particular field as the value of
another field, multiplied by 2.3, but I want the result rounded to 2
decimal places.

So, it would be something like:

update mytable set field1 = ROUND(field2 * 2.3,2)

Does such a function exist in FB 1.0, and if so, what is the exact syntax?

Thanks,
Joe
