here is the shloka..

we all know the devnagri script.Decoding it by denoting numbers to each digit we will have.

- The SlOka in rOman-nAgarE:
*gOpE BAgya maDhu vratha SRnggESO dhaDhesanDhega KalajEvetha Katava galahata rasanDhara*.- The rOman-nAgarE string with only the syllabic consonants:
*g p B y m Dh r th S g S dh Dh s Dh g K l j v th K t v g l h t r s Dh r*.- The katapayAdhe mapping of the consonants:
*3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6 2 1 4 3 3 8 1 2 7 9 2*.- The mapped decimal string is:
*3.14159 26535 89793 23846 2***1***433 8***1***279***2**.- The decimal expansion of
*pi*given by the GNU calculator*bc*: *3.14159 26535 89793 23846 2***6***433 8***3***279***5**.

This gives us the value of pi upto 21 digits.
