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,
then pressing Control-C to copy, and Control-V to paste.

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-27

Septemvigesimal or Radix-27 Number System
Septemvigesimal is a Radix-27 positional notation number system. Radix-27 or Base-27 means that each Septemvigesimal
"digit" represents a multiple of increasing powers of 27, from right to left, such as:
... 27^{3}, 27^{2}, 27^{1}, 27^{0}
The valid Septemvigesimal symbols are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q
Where: A=10, B=11, C=12, D=13, E=14, F=15, G=16, H=17, I=18, J=19, K=20, L=21, M=22, N=23, O=24, P=25, Q=26
For example, the Septemvigesimal number QPN represents the number 19652 in the Decimal number system, like so:
(26 x 27^{2}) + (25 x 27^{1}) + (23 x 27^{0})Applications of Septemvigesimal Systems
A base-27 number system is used in the Telefol language and in the Oksapmin language of Papua New Guinea.
Septemvigesimal notation can be used as a precise and efficient representation of Ternary data, where each Septemvigesimal
digit perfectly represents three Ternary digits.
This is similar to using Octal to represent Binary data, although the Septemvigesimal symbol set is closer in size to the
Hexadecimal symbol set.
