In compound affixes, the numeral two is represented by do- except when it forms part of the numbers 20 (icosa-), 200 (dicta-) or 2000 (dilia-). IUPAC prefers the spelling icosa- for the affix corresponding to the number twenty on the grounds of etymology.

Octal (base 8) is a numeral system with eight as the base. In the decimal system, each place is a power of ten. For example: = + In the octal system, each place is a power of eight. For example:

The octal system represents numbers in base 8, which means that each digit represents a power of 8. Therefore, the 1's place only needs the digits 0-7, and the number 10 in octal (NOT the decimal number 10), is $1\times8^1 + 0\times8^0 = 8$ in decimal.

Octal number system is a base-8 number system where the range of numbers is 0,1,2,3,4,5,6,7. Binary numbers can be grouped into a pair of three to get octal numbers. Learn conversion with examples at BYJU’S.

2025年3月11日 · Octal Number System is a number system with base 8 as it uses eight symbols (or digits) namely 0, 1, 2, 3, 4, 5, 6, and 7. For example, 228, 138, 178, etc. are octal numbers.
