Question: Rounding to zero

Question:Rounding to zero

I have an expression like; 0.7x + 5e-10y, which I would like to approximate to 0.7x.

Round won't work as it will also round the 0.7 down to zero.  I have tried using he Digits command, but it seems to only work half of the time.

Is there a simple command that can put a ceiling on a number like e-5, so that any number lower than that will not be returned?

Cheers;

Robert Ward
