In some cases modp_dtoa/modp_dtoa2 gives different precision then requested

[GoogleCodeExporter]

Nick,

The code has the following branch:

    if (value > thres_max) {
        sprintf(str, "%e", neg ? -value : value);
        return;
    }

This is wrong as it ignores requested precision - sprintf uses 6 precision by 
default.

I think what is going on here is that,

"if the precision is beyond what we can print, use exponential notation"

This may be stupid. and probably should be removed so the output is consistent.
