Question: Display decimal format (in typeset)

Question:Display decimal format (in typeset)

Hi, I'm trying to display a rotation matrix, but due to the interaction with the explore controls and the working numerical precision for the controls / trig terms, I'm getting displays like

1.0  0.0

0.0  -2*10^-10

What I'd like is for the -2*10^-10 to be displayed in decimal format (by default) and therefore would be displayed as 0.0.

So is there a way to control the display formatting of:

x := cos(Pi/(2.0));

so that it displays 0.0 instead of -2*10^-10?

I realise that Increasing the Digits increases the precision, but this simply increases the magnitude of the exponent and I can't simply use x := cos(Pi/(2)), because of the interaction with the explore controls.

Thanks.
