If I write document.write(Math.sqrt(2)) on my HTML page, I get 1.4142135623730951.
Is there any way to make the method output more than 16 decimal places?
No, there is not. Mathematical operations in Javascript are performed using 64-bit floating point values, and 16 digits of precision is right around the limit of what they can represent accurately.
To get more digits of the result, you will need to use an arbitrary-precision math library. I’m not aware offhand of any of these for Javascript that support square roots, though — the one I was able to find offhand (Big.js) only supports addition, subtraction, and comparisons.
