IntMul (NoSQL query)

  • Άρθρο

APPLIES TO: NoSQL

Multiples the values of the left and right operators. For more information, see multiplicative operators.

Syntax

IntMul(<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 {
    multiply: IntMul(5, 2),
    negativeResult: IntMul(5, -2),
    positiveResult: IntMul(-5, -2),
    square: IntMul(5, 5),
    cube: IntMul(5, IntMul(5, 5)),
    multiplyZero: IntMul(5, 0),
    multiplyDecimal: IntMul(5, 0.5)
}

[
  {
    "multiply": 10,
    "negativeResult": -10,
    "positiveResult": 10,
    "square": 25,
    "cube": 125,
    "multiplyZero": 0
  }
]

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).
  • Multiplicative operators have left-to-right associativity.
