Number

Number.abs()

Description: Returns the number’s absolute value, i.e. removes any minus sign

Syntax: Number.abs()

Returns: Number

Source: Custom n8n functionality

Examples:

// x = -1.7
x.abs() //=> 1.7

Number.ceil()

Description: Rounds the number up to the next whole number

Syntax: Number.ceil()

Returns: Number

Source: Custom n8n functionality

Examples:

// x = 1.234
x.ceil() //=> 2

Number.floor()

Description: Rounds the number down to the nearest whole number

Syntax: Number.floor()

Returns: Number

Source: Custom n8n functionality

Examples:

// x = 1.234
x.floor() //=> 1

Number.format()

Description: Returns a formatted string representing the number. Useful for formatting for a specific language or currency. The same as <a href=”https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat/NumberFormat”>Intl.NumberFormat().

Syntax: Number.format(locale?, options?)

Returns: String

Source: Custom n8n functionality

Parameters:

• locale (String) - optional - A <a href=”https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl#locales_argument”>locale tag for formatting the number, e.g. fr-FR, en-GB, pr-BR

• options (Object) - optional - Configuration options for number formatting. More info

Examples:

// number = 123456.789;
number.format('de-DE') //=> 123.456,789

// number = 123456.789;
number.format('de-DE', {'style': 'currency', 'currency': 'EUR'}) //=> 123.456,79 €

Number.isEmpty()

Description: Returns true if the number is 0, NaN, null, or undefined. Returns false for every other number.

isEmpty() isn't a null check. On a number it treats 0 as empty, so {{ $json.count.isEmpty() }} returns true for both a missing field and a field set to 0. To test only for a missing value, compare directly, for example {{ $json.count === null }}, or use the exists operator in the If node.

Syntax: Number.isEmpty()

Returns: Boolean

Source: Custom n8n functionality

Examples:

// num = 10
num.isEmpty() // => false

// num = 0
num.isEmpty() // => true

// num = null
num.isEmpty() // => true

Number.isEven()

Description: Returns true if the number is even. Throws an error if the number isn’t a whole number.

Syntax: Number.isEven()

Returns: Boolean

Source: Custom n8n functionality

Examples:

// number = 33
number.isEven() //=> false

Number.isInteger()

Description: Returns true if the number is a whole number

Syntax: Number.isInteger()

Returns: Boolean

Source: Custom n8n functionality

Examples:

// number = 4
number.isInteger() //=> true

// number = 4.12
number.isInteger() //=> false

Number.isNotEmpty()

Description: Returns true for every number except 0 and NaN. Returns false if the number is 0, NaN, null, or undefined. This is the inverse of isEmpty().

Syntax: Number.isNotEmpty()

Returns: Boolean

Source: Custom n8n functionality

Examples:

// num = 10
num.isNotEmpty() // => true

// num = 0
num.isNotEmpty() // => false

// num = null
num.isNotEmpty() // => false

Number.isOdd()

Description: Returns true if the number is odd. Throws an error if the number isn’t a whole number.

Syntax: Number.isOdd()

Returns: Boolean

Source: Custom n8n functionality

Examples:

// number = 33
number.isOdd() //=> true

Number.round()

Description: Returns the number rounded to the nearest whole number (or specified number of decimal places)

Syntax: Number.round(decimalPlaces?)

Returns: Number

Source: Custom n8n functionality

Parameters:

• decimalPlaces (Number) - optional - The number of decimal places to round to

Examples:

// number = 1.256
number.round() //=> 1

// number = 1.256
number.round(1) //=> 1.3
number.round(2) //=> 1.26

Number.toBoolean()

Description: Converts the number to a boolean value. 0 becomes false; everything else becomes true.

Syntax: Number.toBoolean()

Source: Custom n8n functionality

Examples:

// number = 12
number.toBoolean() //=> true

// number = 0
number.toBoolean() //=> false

Number.toDateTime()

Description: Converts a numerical timestamp into a DateTime. The format of the timestamp must be specified if it’s not in milliseconds. Uses the time zone in n8n (or in the workflow’s settings).

Syntax: Number.toDateTime(format?)

Returns: DateTime

Source: Custom n8n functionality

Parameters:

• format (String) - optional - The type of timestamp to convert. Options are ms (for Unix timestamp in milliseconds), s (for Unix timestamp in seconds) or excel (for days since 1900).

Examples:

// ts = 1708695471
ts.toDateTime('s') //=> 2024-02-23T14:37:51+01:00

// ts = 1708695471000
ts.toDateTime('ms') //=> 2024-02-23T14:37:51+01:00

// ts = 45345
ts.toDateTime('excel') //=> 2024-02-23T01:00:00+01:00

Number.toLocaleString()

Description: Returns a localised string representing the number, i.e. in the language and format corresponding to its locale. Defaults to the system's locale if none specified.

Syntax: Number.toLocaleString(locales?, options?)

num.toLocaleString() //=> '500,000.125' (if in US English locale)

// num = 500000.125
num.toLocaleString('fr-FR') //=> '500 000,125'

// num = 500000.125
num.toLocaleString('fr-FR', {style:'currency', currency:'EUR'}) //=> '500 000,13 €'

Number.toString()

Description: Converts the number to a simple textual representation. For more formatting options, see toLocaleString().

Syntax: Number.toString(radix?)

Returns: String

Source: JavaScript function

Parameters:

• radix (Number) - optional - The base to use. Must be an integer between 2 and 36. E.g. base 2 is binary and base 16 is hexadecimal.

Examples:

// num = 500000.125
num.toString() //=> '500000.125'

// num = 500000.125
