This is You will be astounded by the power of Sanskrit in expressing mathematical formula. One simple Sanskrit poem to learn and you know pie up to 32 decimal places..
What a glory of ancient India!

gopi bhaagya madhuvrata srngiso dadhi sandhiga
khala jeevit khatava gala hala rasandara

While this verse is a type of petition to Krishn, when learning it one can also learn the value of pi/10 (ie the ratio of the circumference of a circle to its diameter divided by 10) to 32 decimal places. It has a self-contained master-key for extending the evaluation to any number of decimal places.

The translation is as follows:
O Lord anointed with the yogurt of the milkmaids' worship (Krishna), O savior of the fallen, O master of Shiv, please protect me.

Vowels make no difference and it is left to the author to select a particular consonant or vowel at each step. This great latitude allows one to bring about additional meanings of his own choice. For example kapa, tapa, papa, and yapa all mean 11.

By a particular choice of consonants and vowels one can compose a poetic hymn with double or triple meanings. Here is an actual Sootra of spiritual content, as well as secular mathematical significance.

The Sanskrit consonants
ka, ta, pa, and ya all denote 1;
kha, tha, pha, and ra all represent 2;
ga, da, ba, and la all stand for 3;
Gha, dha, bha, and va all represent 4;
gna, na, ma, and sa all represent 5;
ca, ta, and sa all stand for 6;
cha, tha, and sa all denote 7;
ja, da, and ha all represent 8;
jha and dha stand for 9; and
ka means zero.

At the same time, by application of the consonant code given above, this verse directly yields the decimal equivalent of pi divided by 10 : pi/10 =
0.31415926535897932 384626433832792.

Thus, while offering Maantrik praise to Godhead in devotion, by this method one can also add to memory significant secular truths.
