$max

$max operator helps you in finding the maximum value in an given array expression. You can use this in any Expression Object.

Syntax

{
    "$max":[ <expr>, <expr> ... ]
}

Properties

Field	Description	Required
<expr>	The <expr> expression can be any valid expression as long as it resolves to a number. It can also be a Magical Autocomplete.	true

Returns

float - The result of $max operation

Examples

Basic example

{
    "$max": [1,5,3,6,2]
}

The above expression returns 6

With Nested Expressions

{
    "$max": [
        1,
        2,
        { "$add" : [1,2] },
        { "$pow" : [2,2] },
    ]
}

The above expression calculates the nested expression, return 3,4 respectively in its place and then the outer $max expression returns 4 overall.

With Magical Autocomplete

Let's say we have declared a variable temp in our API flow, which has a value of [5, 4, 3, 2, 1] currently.

{
    "$max":"$.variables.temp"
}

The above expression would resolve to a result of 5
