Function Round() on 7.3 and 7.4

Hi everyone,=20

I have always used the numeric function round on 7.2 version but on the
7.3 and 7.4 versions its not there. What's happening ?
=20
Can I copy the source from 7.2 and compile on 7.3 or 7.4 version ? Do I
have another choice to solve this ?=20

Thanks in advance
