decNumberToString/decToString and scientific notation   

Hi,

I have a somewhat urgent question about the decNumberToString/decToString and when it switches from plain to scientific notation.

0.000001 will result in a plain "0.000001" but 0.0000001 will result in 1E-7
I need the switch to occur at precisions of 10 decimal places or so.

I looked at the source for decToString and it does seem to be decided by the hard coded value here...

if ((exp>0) || (pre<-5)) { // need exponential form

I appears that it would be ok to simply change the 5 to a larger value but I would like some confirmation that this won't introduce problems.

Can you help Mike?

thanks,

James
