+# String And Int Operations
+The importance of various number like binary numbers, hexadecimals, ASCII values are well known.
+
+Hence, this file aims to simply and aid in the process of conversion to required result within a tap of few buttons by the help of extensions.
+
+## Binary Numbers
+A base-2 numerical system where an integer is defined using only 1's and 0's
+Example : 13 in binary is 1101
+
+## Hexadecimal Numbers
+A system of representation of numbers where the radix present is 16 i.e. the numbers used in this system range from 0...9 & A,B,C,D,E,F.
+Example : 10 in hexadecimal is a
+
+## ASCII
+A method adapted that represents characters as numbers
+Example : 'a'(lowercase) in terms of ASCII code is 97
+
+## Implementation
+```swift
+let value = "10".intToHex // returns "10" as Hexadecimal
+print(value) // prints "a"
+```
+
+```swift
+let value = "A".ascii // returns "A" as Ascii value
+print(value) // prints 65
+```
+
+```swift
+let value = 13.binString // returns 13 as Binary String
+print(value) // prints "1101"
+```
+
+```swift
+let value = 97.intToAscii // returns 97 as a character taking in the integer as ASCII value
+print(value) // prints "a"
+```
