/**
|
|
* Create a parser. The function creates a new `math.Parser` object.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.parser()
|
|
*
|
|
* Examples:
|
|
*
|
|
* const parser = new math.parser()
|
|
*
|
|
* // evaluate expressions
|
|
* const a = parser.evaluate('sqrt(3^2 + 4^2)') // 5
|
|
* const b = parser.evaluate('sqrt(-4)') // 2i
|
|
* const c = parser.evaluate('2 inch in cm') // 5.08 cm
|
|
* const d = parser.evaluate('cos(45 deg)') // 0.7071067811865476
|
|
*
|
|
* // define variables and functions
|
|
* parser.evaluate('x = 7 / 2') // 3.5
|
|
* parser.evaluate('x + 3') // 6.5
|
|
* parser.evaluate('f(x, y) = x^y') // f(x, y)
|
|
* parser.evaluate('f(2, 3)') // 8
|
|
*
|
|
* // get and set variables and functions
|
|
* const x = parser.get('x') // 7
|
|
* const f = parser.get('f') // function
|
|
* const g = f(3, 2) // 9
|
|
* parser.set('h', 500)
|
|
* const i = parser.evaluate('h / 2') // 250
|
|
* parser.set('hello', function (name) {
|
|
* return 'hello, ' + name + '!'
|
|
* })
|
|
* parser.evaluate('hello("user")') // "hello, user!"
|
|
*
|
|
* // clear defined functions and variables
|
|
* parser.clear()
