console.log(dollarString.valid("$10.2"));  //TRUE
console.log(dollarString.valid("$5"));     //TRUE
console.log(dollarString.valid("1.00"));   //TRUE

console.log(dollarString.valid("$1.004")); //FALSE
console.log(dollarString.valid("$1.00c")); //FALSE
console.log(dollarString.valid("$1.a0"));  //FALSE

dollarString.toCents(value)

console.log(dollarString.toCents("$1.00")); // 100
console.log(dollarString.toCents('$2.22')); // 222
console.log(dollarString.toCents('$1.50')); // 150

dollarString.toDollars(value)

console.log(dollarString.toDollars("$1.00")); // 1
console.log(dollarString.toDollars('$2.22')); // 2.22
console.log(dollarString.toDollars('$1.50')); // 1.5

dollarString.fromCents(value)

console.log(dollarString.fromCents(100)); // '$1.00'
console.log(dollarString.fromCents(222)); // '$2.22'
console.log(dollarString.fromCents(150)); // '$1.50'

dollarString.fromDollars(value)

console.log(dollarString.fromDollars(1));    // '$1.00'
console.log(dollarString.fromDollars(2.22)); // '$2.22'
console.log(dollarString.fromDollars(1.5));  // '$1.50'

dollarString.compare(val1, val2)

  • -1 if val1 is smaller than val2

console.log(dollarString.compare("$1.00", "$2.00"));  // -1
console.log(dollarString.compare("$10.00", "$10"));   // 0
console.log(dollarString.compare("$2.00" , "$1.00")); // 1

console.log(dollarString.multipleOf("$2.00", "$1.25"));  // false
console.log(dollarString.multipleOf("$10.00", "$1"));   // true
