# ASCII,Hex,Binary,Decimal,Base64 Converter

### ASCII:

ASCII stands for "American Standard Code for Information Interchange". The computer understands only numbers (0,1) to understand alphabets ASCII codes used. The list of 128 ASCII encodes characters which include 95 printable characters arranged into 7-bit integers. The printable characters include digits 0 - 9, lower letters a to z, upper letters A to Z and symbols.

### Example:

In ASCII encodes lower letter "m" represent in the binary format as "01001101", Hexadecimal as "4D” and decimal as "109".

A hexadecimal number is also called base-16 number system cause it has 16 digits in it form 0 to 9 & A to F. In computer languages coding it makes easy to write large numbers. Example for hexadecimal is 4B6.

### Binary:

A binary number system having to numbers "O", "1" and it is known as Base-2 number system. The base-2 number system used in digital electronics to write instruction for electronic equipment and invented by Gottfried Leibniz. In this zero represents OFF, 1 represents ON cause electronic equipment used gates. Example of a binary number is 10110.

### Decimal:

A decimal number system is also called a Base-10 (Hindu Arabic) number system. In this system 10 digits used they are 0,1, 2, 3, 4, 5, 6, 7, 8, 9. In this system, we can write fractional numbers. Example of a decimal number is 129.56.

### Base64:

It is a binary to ASCII converter with a base64 format that introduces from MIME encoding scheme. Base64 used to keep data unchanged while transfers over media (ex: mail). For base64 different type of implementation follows but for MIME use for first 62 values lower case a-z, uppercase A-Z, and numbers 0-9. In other base64 implementation use different symbols for last two digits.
