When I type sqrt(3) and sqrt(99) I do not get the same result as https://www.mathsisfun.com/irrational-numbers.html, is there some function which allows me to view the mathematical proof of the square root function for irrational numbers?

Sorry just an idiosyncratic question.

If you want to have some fun and see more digits, then  try the symbolic package like this:

pkg load symbolic

digits(100)

a3=vpa(3)

a99=vpa(99)

sq3=sqrt(a3)

sq99=sqrt(a99)

 my answer looks like this:

a3 = (sym)

  3.0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

  00000000

a99 = (sym)

  99.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
