The Art of Calculation

In the grand tapestry of existence, numbers dance and intertwine, spinning a rhythm of reason that orchestrates the universe. You are tasked with crafting an exquisite instrument, a Calculator, to join this cosmic ballet.

Here are the instructions for this exercise:

Instructions

  1. Setup:
  • Define a class named Calculator. The constructor of the class should have two properties:
    • PI which is equal to Math.PI
    • E which is equal to Math.E
  1. Methods:

  • Implement the following methods:

    • percentage(x, y): This method should take two parameters - x and y. Calculate the percentage of x in y and return it as a string with a '%' sign. If y is zero, return the error message 'Error: Divisor cannot be zero'.

    • add(x, y): This method should take two parameters - x and y. Return the sum of x and y.

    • subtract(x, y): This method should take two parameters - x and y. Return the difference of it (y - x).

    • multiply(x, y): This method should take two parameters - x and y. Return the product of x and y.

    • divide(x, y): This method should take two parameters - x and y. Return the quotient of x divided by y. If y is zero, return the error message 'Error: Divisor cannot be zero'.

    • remainder(x, y): This method should take two parameters - x and y. Return the remainder of x divided by y. If y is zero, return the error message 'Error: Divisor cannot be zero'.

    • powerOf(x, y): This method should take two parameters - x and y. Return the power of x raised to y.

    • sqrt(x): This method should take one parameter - x. Return the square root of x. If x is a negative number, return the error message 'Error: Cannot calculate the square root of a negative number'.

Notes

  • Remember to handle edge cases, such as division by zero and square root of a negative number.
  • Ensure that all strings returned are in the exact format as specified in the instructions.

Examples:

console.log(calc.percentage(3, 12)); // 25%
console.log(calc.add(5, 7)); // 12
console.log(calc.subtract(5, 7)); // 2
console.log(calc.multiply(5, 7)); // 35
console.log(calc.divide(35, 7)); // 5
console.log(calc.modulate(7, 5)); // 2
console.log(calc.powerOf(5, 3)); // 125
console.log(calc.sqrt(25)); // 5
