ekadhikena purvena of 1/9,1/19,1/29,1/39....... astounding idea vedic math

The Vedic Mathematics way : by using the Sutra ekadhiken Purvena which means "by one more than the previous one" and can be used when the denominator ends in 9. so with the help of this numbers of the form 1/9,1/19,1/29,1/39.............. can be computed Guys just enter any number which has unit digit 9 for example if you type 6199 ,it will calculate 1/6199.
for e.g if you type 19 it will calculate 1/19
1/19=0.052631578947368421052631578947368421052631...................
after 18 digits the numbers are repeated.
similarly for
1/29=0.03448275862068965517241379310344827586206896551724137931034482........
after 28 digits the numbers are repeated.
but for
1/39=0.0256410256410256410256...................
after 6 digits the numbers are repeated.
and for
1/49=0.0204081632653061224489795918367346938775510204081632.........
after 42 digits the numbers are repeated.
and for
1/1729=0.00057836899942163100057836899942163100057836..................
after 18 digits the numbers are repeated
but for bigger numbers you can't check in calculator and in those case this program may help you
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=13414&lngWId=3
Note:
After downloading only two simple modifications are required ,the first one is
remove these four lines
if(n==49)

y=21;

if(n==289)

y=136;

and replace it by
if((n==49)||(n==289)||(n==2209)||(n==4489)||(n=9409))

y=(sqrt(n)*((sqrt(n)-1)))/2;

and in order to use the sqrt function include the header file
#include<math.h>
so that program will work flawlessly
but any number of the above form will repeat after certain digits but some numbers will take more digits whereas some will take less
for e.g if you give 99 it will display 0.101 (i.e it will repeat after 3 digits itself)
whereas if you give 5789 see after how many digits it will repeat
After 2478 digits the same digits repeats
so answer(recurring decimal) is 0.000172741406115045776472620487130765244429089
