javascript - More accurate value of Pi?

Question

I type Math.PI; in Chrome Console and this is returned:

3.141592653589793

Then I type Math.PI - 3.14159265358

Answer 1

I don't see why you would need PI to such accuracy but you can either :

a) Calculate PI yourself using Leibniz formula

b) Define PI yourself (using this library)

var PI = new bigdecimal.BigDecimal("3.141592653589793238462643383279");

You can find first 100,000 digits of PI here if you really need it.
