IntSub (NoSQL query)

  • Article

APPLIES TO: NoSQL

Subtracts the value of the right-hand operand from the left-hand operand. For more information, see additive operators.

Syntax

IntSub(<int_expr_1>, <int_expr_2>)

Arguments

Description
int_expr_1 An integer expression, which is used as the left-hand operand.
int_expr_2 An integer expression, which is used as the right-hand operand.

Return types

Returns a 64-bit integer.

Note

For more information, see __int64.

Examples

This example tests the function with various static values.

SELECT VALUE {
    negativeResult: IntSub(25, 50),
    positiveResult: IntSub(25, 15),
    subtractSameNumber: IntSub(25, 25),
    subtractZero: IntSub(25, 0),
    subtractDecimal: IntSub(25, 2.5)
}

[
  {
    "negativeResult": -25,
    "positiveResult": 10,
    "subtractSameNumber": 0,
    "subtractZero": 25
  }
]

Remarks

  • This function expects integers for both arguments and performs operations assuming the values are a 64-bit integer.
  • If any of the arguments aren't an integer, the function returns undefined.
  • Overflow behavior is similar to the implementation in C++ (wrap-around).
