How To Use This Converter
Type a number in any of the Number-Base Radix input fields and press Enter or Return on your keyboard or keypad.
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-4

Quaternary or Radix-4 Number System
Quaternary is a Radix-4 positional notation number system. Radix-4 or Base-4 means that a Quaternary
"digit" (called a Crumb), represents a multiple of increasing powers of 4, from right to left, such as:
... 4^{3}, 4^{2}, 4^{1}, 4^{0}
The valid Quaternary symbols are:
0, 1, 2, 3
For example, the Quaternary number 302 represents the number 50 in the Decimal number system, like so:
(3 x 4^{2}) + (0 x 4^{1}) + (2 x 4^{0})History of the Quaternary Number System
Many or all of the now extinct Chumashan languages originally used a base-4 counting system, in which
the names for numbers were structured according to multiples of 4 and 16, not 10.
Chumashan was a family of languages that were spoken on the southern California coast, from San Luis Obispo to Malibu,
in neighboring Coastal and Transverse range valleys bordering the San Joaquin Valley, and on the adjacent Channel
islands of San Miguel, Santa Rosa, and Santa Cruz.
Parallels can be drawn between Quaternary numerals and the way genetic code is represented by DNA.
The four DNA nucleotides in alphabetical order, abbreviated A, C, G and T, can be represented by the
Quaternary digits 0, 1, 2, and 3.

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.
