NumberBin (NoSQL query)

  • आलेख

APPLIES TO: NoSQL

Rounds the numeric expression's value down to a multiple of specified bin size.

Syntax

NumberBin(<numeric_expr> [, <bin_size>])

Arguments

Description
numeric_expr A numeric expression, which is evaluated and then the resulting value is rounded to a multiple of the specified bin size.
bin_size (Optional) A numeric value that specifies the bin size to use when rounding the value. This numeric value defaults to 1 if not specified.

Return types

Returns a numeric value.

Examples

This first example bins a single static number with various bin sizes.

SELECT VALUE {
    roundToNegativeHundreds: NumberBin(37.752, -100),
    roundToTens: NumberBin(37.752, 10),
    roundToOnes: NumberBin(37.752, 1),
    roundToZeroes: NumberBin(37.752, 0),
    roundToOneTenths: NumberBin(37.752, 0.1),
    roundToOneHundreds: NumberBin(37.752, 0.01)
}

[
  {
    "roundToNegativeHundreds": 100,
    "roundToTens": 30,
    "roundToOnes": 37,
    "roundToOneTenths": 37.7,
    "roundToOneHundreds": 37.75
  }
]

This next example uses a field from an existing item.

[
  {
    "name": "Ignis Cooking System",
    "price": 155.23478,
    "category": "portable-cooking"
  }
]

This query rounds the previous field using the function.

SELECT
    p.name,
    NumberBin(p.price, 0.01) AS price
FROM
    products p
WHERE
    p.category = "portable-cooking"

[
  {
    "name": "Ignis Cooking System",
    "price": 155.23
  }
]

Remarks

  • This function returns undefined if the specified bin size is 0.
  • The default bin size is 1. This bin size effectively returns a numeric value rounded to the next integer.
