Integer is perfect square

integer-is-perfect-square · version 1.0.0 · Numbers & math · free, no key needed

Test whether a non-negative integer string is a perfect square.

Use when you need to: integer is perfect square · perfect square test · check if a number is a perfect square.

Supported

• integer is perfect square
• perfect square test
• check if a number is a perfect square

Not supported

• negative input
• floating-point square root
• nth power test

Behavior

• value is a canonical non-negative integer string: 0 or a non-zero leading digit followed by digits, at most 1000 digits.
• Negative values are rejected.
• 0 and 1 are perfect squares (0*0 and 1*1).
• is_perfect_square is computed exactly via integer floor square root (no floating point), never approximated.

Input

• value (string, required): max length 1000; pattern ^(0|[1-9][0-9]*)$

Output

• is_perfect_square (boolean, required)

Limits

• max digits: 1000

Example

Request input:

{
  "value": "49"
}

Response:

{
  "result": {
    "is_perfect_square": true
  }
}
