Syntax

$sqrt[value]

Parameters

Parameter	Type	Required	Description
value	number	Yes	The number to calculate the square root of. ≥ 0.

Behavior

• Exactly one argument is required. A value that is not a finite number (text, empty) raises the error “Expected a finite number in argument 1.”.
• For perfect squares, the result is an integer: $sqrt[16] → 4.
• Unless decimals are enabled with $enableDecimals[yes], the result is rounded to the nearest integer: $sqrt[2] → 1, $sqrt[2.25] → 2.
• With $enableDecimals[yes], the decimal result is kept: $sqrt[2] → 1.4142135623730951, $sqrt[2.25] → 1.5.
• For 0, it returns 0.
• For a negative number, the call fails with the error “Square root requires a non-negative number.”.

Examples

Square Root Calculation

$title[Math: Square Root]
$description[Square root of `16`: **$sqrt[16]**]
$addField[Square root of 25;$sqrt[25];yes]
$enableDecimals[yes]
$addField[Non-integer root ($sqrt[2]);$sqrt[2];yes]
$color[#5865F2]

Notes

• Negative numbers are an error.
• $enableDecimals should be set before the $sqrt[] calls it must affect.
• For powers (squaring), use $calculate[value^2] or $multi[value;value].
• For other roots (cube root, etc.), $calculate[value^(1/3)] can be used (for example $calculate[8^(1/3)] → 2).
• With decimals enabled the value is a double-precision number.
