llvm.js/expression (RunKit + npm)
Expression Component Documentation
The expression component in llvm.js allows you to evaluate mathematical expressions and obtain the answer using the answer()
method. This component supports the following features:
- Parentheses and nested parentheses to control the evaluation order.
- The constant value of π (pi).
- Basic arithmetic operations such as addition, subtraction, multiplication, and division.
- Exponentiation using the
^
operator.
Installation
To use the expression component, you first need to install the llvm.js
package. You can do this using npm:
npm i llvm.js
Usage
- Import the
Expression
class from thellvm.js/expression
module:
const Expression = require('llvm.js/expression');
- Create a new instance of the
Expression
class by providing the mathematical expression as a parameter:
let expression = new Expression('2 + 4');
- Use the
answer()
method to evaluate the expression and obtain the answer:
console.log(expression.answer());
The above code will output 6
, which is the result of evaluating the expression 2 + 4
.
Examples
Here are some examples to demonstrate the usage of the expression component:
- Evaluating a complex expression:
let expression = new Expression('(8 - 4) * (6 / 2)');
console.log(expression.answer()); // Output: 12
- Using the constant value of π (pi):
let expression = new Expression('pi * 2');
console.log(expression.answer()); // Output: 6.28
- Performing exponentiation:
let expression = new Expression('2 ^ 3');
console.log(expression.answer()); // Output: 8
Note: The expression component supports more complex mathematical operations. Refer to the official documentation for a complete list of supported features and usage examples.
We hope this documentation helps you effectively use the expression component in the llvm.js project. Please feel free to reach out if you have any further questions or need additional assistance.
