The other Number-Base Radix fields will show the number you entered, converted to the other radixes.
TIP:Entry Errors
If the data you type into any Base field contains disallowed symbols for that field, the converter will notify you.
In that case, simply re-type valid data in the field of your choice and press Enter or Return.
TIP:Copy and Paste
You can Copy and Paste any of the fields by selecting the text in the field,

Radix-10

Decimal or Radix-10 Number System
Decimal is a Radix-10 positional notation number system. Radix-10 or Base-10 means that each Decimal "digit"
represents a multiple of increasing powers of 10, from right to left, such as:
... 10^{3}, 10^{2}, 10^{1}, 10^{0}
The valid Decimal symbols are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
For example, the Decimal number 927 represents the following numerical expression:
(9 x 10^{2}) + (2 x 10^{1}) + (7 x 10^{0})History of the Decimal Number System
The modern Decimal number system, known as the Hindu-Arabic number system, originated in India around the 9th century CE.
The system spread to the western world during the Middle Ages (1000 to 1300 CE) as a result of trade.
Some scholars attribute the first documented use of a Decimal system to China in the 1st century BCE.

Radix-16

Hexadecimal or Radix-16 Number System
Hexadecimal is a Radix-16 positional notation number system. Radix-16 or Base-16 means that each Hexadecimal "digit"
represents a multiple of increasing powers of 16, from right to left, such as:
... 16^{3}, 16^{2}, 16^{1}, 16^{0}
The valid Hexadecimal symbols are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,A, B, C, D, E, F
Where: A=10, B=11, C=12, D=13, E=14, F=15
For example, the Hexadecimal number FE8 represents the number 4072 in the Decimal system, like so:
(15 x 16^{2}) + (14 x 16^{1}) + (8 x 16^{0})Applications of Hexadecimal Number System
A Hexadecimal digit perfectly represents 4 Binary digits (bits), often called a "Nibble".
The principal use of Hexadecimal notation is in displaying to humans the Binary values used in computing and digital electronics.
For example, byte values (8-bits) can range from 0 to 255 Decimal, but are more efficiently represented as two
Hexadecimal digits in the range 00 through FF.
Hexadecimal is commonly used to represent computer memory addresses and memory contents, CPU register values,
computer colors, computer character encodings, and many other values that are routinely used in modern computers and digital electronics.
