Semantic Square Root is a lightweight js package that is able to represent a stored square root value as both a decimal value of the square root and a rationalized version with the square root symbol. E.g. "√3" and "1.732...".
At this time Semantic Square Root is on NPM with planned JSR support in the near future.
npm install semantic-square-rootIn order to use this as a module it must first be imported.
import sqrt from "semantic-square-root";There are three ways to switch between the decimal and symbol representation of a defined square root:
This method is the easiest to understand and creates readable code, however in a more complex context it is too long. Due to this, it is recommend only when using the value individually.
const foo = sqrt(9);
console.log(String(foo)); // √9
console.log(Number(foo)); // 3This is the most common use of this package. Javascript will automatically convert the type of the value depending on the context around it. E.g. string concatenation v.s. addition.
const bar = sqrt(9);
console.log(`${bar}`); // √9
console.log(bar + 0); // 3To support the above methods, the square root object contains two methods: toString() and valueOf(). Calling these two methods can result in the intended behavior, however it is longer and less readable than method one, so it is not recommended.
const baz = sqrt(9);
console.log(baz.toString()); // √9
console.log(baz.valueOf()); // 3
