This is build upon Math function of common javascript

Using this, you can do this with numbers:

• add()
• addMore()
• multiply()
• multiplyMore()
• divide()
• divideMore()
• minus()
• minusMore()
• percent()
• fix()
• squareOf()
• getPct()
• generateRandom()
• positive()
• negative()
• compare()
• power()
• isPositive()
• isNegative()
• getMax()
• getMin()
• restrictBetween()
• isPrime()
• average()
• median()
• mode()
• toRoman()
• formatWithCommas()

you can do this with arrays

• shuffleArray()
• uniqueInArray()

you can also check leap year as well by using

• isLeapYear()
