Equation six figures limite ?

Hi,

I'm using many equations in an assembly to drive my design (SolidWorks 11). It seems that Solidworks won't evaluate my equation to a precision higher than 6 figures. I mean the total number of digit on each side of the period has to be 6 or less.

See screen grab below :

The question is : Is there any way  to have equation evaluated to more than 6 digits ?

I tried Tools>Option>Documents properties>Units but it didn't help.

As shown above using e =  Format(1234.56789,"####.####") won't work neither.

Anyone any idea ?

Thanks
