Integer add

integer-add · version 1.0.0 · Numbers & math · free, no key needed

Add two canonical signed integer strings and return their canonical sum.

Use when you need to: integer add · add two integers · sum two integer strings.

Supported

• integer add
• add two integers
• sum two integer strings

Not supported

• decimal add
• floating point add
• integer multiply
• scientific notation
• locale digit grouping
• hexadecimal add

Behavior

• Inputs a and b are signed base-10 integer strings parsed with BigInt.
• A canonical integer is 0 or an optional ASCII minus followed by a non-zero leading digit and only digits after that.
• Input -0 is accepted and canonicalized to 0; +, spaces, underscores, hex, exponents, empty strings, and other leading zeros are rejected.
• The output value is the canonical integer string of a + b.
• Each input and the sum may have at most 1000 digits excluding the sign.

Input

• a (string, required): max length 1001; pattern ^-?(0|[1-9][0-9]*)$
• b (string, required): max length 1001; pattern ^-?(0|[1-9][0-9]*)$

Output

• value (string, required): max length 1001; pattern ^(0|-?[1-9][0-9]*)$

Limits

• max digits: 1000

Example

Request input:

{
  "a": "19",
  "b": "23"
}

Response:

{
  "result": {
    "value": "42"
  }
}
