OK so this is bizarre to me…
All my courses sum the price correctly, EXCEPT if a dish is priced at $X.95 or $X.96 !
See below my code for example.
Run this and you shall see.
let menu = {
_courses: {
appetizers: [],
mains: [],
desserts: []
},
get appetizers() {
return this._courses.appetizers;
},
set appetizers(appetizersIn) {
this._courses.appetizers = appetizersIn;
},
get mains() {
return this._courses.appetizers;
},
set mains(mainsIn) {
this._courses.mains = mainsIn;
},
get desserts() {
return this._courses.appetizers;
},
set desserts(dessertsIn) {
this._courses.desserts = dessertsIn;
},
get courses() {
return {
appetizers: this.appetizers,
mains: this.mains,
desserts: this.desserts,
}
},
addDishToCourse(courseName, dishName, dishPrice) {
const dish = {
name: dishName,
price: dishPrice
};
this._courses[courseName].push(dish);
},
getRandomDishFromCourse(courseName) {
const dishes = this._courses[courseName];
const randomIndex = Math.floor(Math.random() * dishes.length);
return dishes[randomIndex]
},
generateRandomMeal() {
const appetizer = this.getRandomDishFromCourse('appetizers');
const main = this.getRandomDishFromCourse('mains');
const dessert = this.getRandomDishFromCourse('desserts');
const totalPrice = appetizer.price + main.price + dessert.price;
return `Your meal is ${appetizer.name}, ${main.name}, ${dessert.name}. The price is $${totalPrice}.`
}
};
// menu.addDishToCourse('appetizers', 'Caesar Salad', 4.25)
menu.addDishToCourse('appetizers', 'Buffalo Wings', 8.42)
// menu.addDishToCourse('appetizers', 'Jazz Balls', 2.00)
// menu.addDishToCourse('mains', 'Chicken Parmesan', 10.50)
menu.addDishToCourse('mains', 'Steak', 12.95)
// menu.addDishToCourse('mains', 'Pizza', 20.25)
menu.addDishToCourse('desserts', 'Chocalate Ice Cream', 4.25)
// menu.addDishToCourse('desserts', 'Vanilla Ice Cream', 4.25)
// menu.addDishToCourse('desserts', 'Strawberry Ice Cream', 4.25)
let meal = menu.generateRandomMeal();
console.log(meal)
8.42+12.95+4.25 = $25.62
but in this program,
8.42+12.95+4.25. = $25.619999999999997.
How this math could give a repeating decimal is beyond me.
I have commented out the other items (as this exercises functions use random) so you can replicate the issue immediately.
All help is appreciated!
