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.,
trueorfalse,1or0) - 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

i,n,x,y;main(){scanf("%i",&x);y=1,n=10001;int z[n];for(i=0;i<n;i++,y++){z[i]=pow(y,2);}for(i=0;i<n;i++){if(x==z[i]){puts("True");break;}if(x!=z[i]&&i==n-1){puts("False");}}}
If libraries also count in the code, the total byte count will be 226 218 213 210.
