sqrt - Compute the square root of a value

sqrt is a fundamental function in mathematics. It calculates the square root of a given value.

Note

It is the inverse of power(number, 2)

Syntax

Like many functions in DataPrime, sqrt supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.

Function notation

sqrt(number: number): number

Method notation

number: number.sqrt(): number

Arguments

Name	Type	Required	Description
number	number	true	The number whose square root we seek

Example - Computing "Rate of Return" over 2 years

Consider the following document:

{
    "buyer": "Chris",
    "asset": "DataDog",
    "bought_at_price": 100,
    "sold_at_price": 10
}

The above document represents a trade that occurred in a financial service. We can use the sqrt function to aid us in computing the rate of return:

Function notation

create ror from (sqrt(sold_at_price / bought_at_price) - 1)

Method notation

create ror from ((sold_at_price / bought_at_price).sqrt() - 1)

This will result in the following document:

{
    "buyer": "Chris",
    "asset": "DataDog"
    "bought_at_price": 100,
    "sold_at_price": 10,
    "ror": -0.683772233983162
}

round
