It's Hip to be Square

Challenge

A catalogue type challenge that simply asks: Given an integer n (where n>=0) as input return a truthy value if n is a perfect square or a falsey value if not.


Rules

  • You may take input by any reasonable, convenient means.
  • You need not handle inputs greater than what your chosen language can natively handle nor which would lead to floating point inaccuracies.
  • Output should be one of two consistent truthy/falsey values (e.g., true or false, 1 or 0) - truthy if the input is a perfect square, falsey if it's not.
  • This is code-golf so lowest byte count wins.

Test Cases

Input:  0
Output: true

Input:  1
Output: true

Input:  64
Output: true

Input:  88
Output: false

Input:  2147483647
Output: false

Shaggy‭ Afaik there isn't an online runner for this language. If you want, the reference intepreter lives at https://github.com/Timwi/EsotericIDE

Does it translate directly to Golfscript? If so, could you add a TIO for that? So's we can verify the results.

Shaggy‭ I don't think it does.
