yes but i'm a little ot because it is C++...

my sys change the precision of all the floats
and the time is too much [1 or 2 minuts] because if change the precision of
floats
all costants are recalculated for the new precision
(among these there is "e" too)

Something as:
[i don't know if it is right]
#include "dlluse.h"

int  daie(fnum*  z, int  prec)
{fnum  y, k;
 int p, p10;

 if(z==0||prec<0)  R  0;

 set_precision10(prec);
 ooo.precision(prec);

 y=1; k=2; *z=2;
 F(;;){y = y/k;
       if(y==0)  break;
       *z+=y; k+=1;
      }
 R   1;
}

int main27(void)
{fnum   r, z;
 int    g;

 if(daie(&z, 10)==0) {P("Errore");   R  0;}
 else {ooo<<"z= "<< z<<"\n"; }
 if(daie(&z, 50)==0) {P("Errore");   R  0;}
 else {ooo<<"z= "<< z<<"\n"; }
 if(daie(&z, 100)==0) {P("Errore");  R  0;}
 else {ooo<<"z= "<< z<<"\n"; }
 if(daie(&z, 1000)==0) {P("Errore"); R  0;}
 else {ooo<<"z= "<< z<<"\n"; }
 if(daie(&z, 2000)==0) {P("Errore"); R  0;}
 else {ooo<<"z= ";
         // here if not use the below scrivi()
         // print  1000 digits and not 2000
         // i think it is for buffer on ooo
       scrivi(ooo, z, 2000, 2000, 0);
       ooo<<"\n";
      }
 if(daie(&z, 4000)==0) {P("Errore"); R  0;}
 else {ooo<<"z= ";
       scrivi(ooo, z, 4000, 4000, 0);
       ooo<<"\n";
      }
 R 0;
}

int  main(void)
{/* open close the dll call main27*/
}
