I type Math.PI;
in Chrome Console and this is returned:
3.141592653589793
Then I type Math.PI - 3.141592653589793;
and 0
was returned.
Is there a way to get a more accurate value (such as 3.1415926535897932384
) of Math.PI
in Javascript?
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.
The maximum decimal places in javascript is limited to 15
.
So you cannot get more than 15 decimal places.
But you can get up to 20 decimal places by doing but its not accurate
Math.PI.toFixed(20); //3.14159265358979311600
That will give you a PI value with 20 decimal places.
Note: 20
is the maximum and 0
is the minimum for toFixed()
.
So trying Math.PI.toFixed(100)
will throw an error.
