In mathematics, change of base can mean any of several things: . Changing numeral bases, such as converting from base 2 to base 10 ().This is known as base conversion.; The logarithmic change-of-base formula, one of the logarithmic identities used frequently in algebra and calculus.
Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89: Largest base for which all left-truncatable primes are known. 90: Nonagesimal: Related to Goormaghtigh conjecture for the generalized repunit numbers (111 in base 90 = 1111111111111 in base 2). 95: Number of printable ASCII characters ...
For example, in the decimal system (base 10), the numeral 4327 means (4×10 3) + (3×10 2) + (2×10 1) + (7×10 0), noting that 10 0 = 1. In general, if b is the base, one writes a number in the numeral system of base b by expressing it in the form a n b n + a n − 1 b n − 1 + a n − 2 b n − 2 + ... + a 0 b 0 and writing the enumerated ...
The base can also be used to show the relationship between the side of a square to its diagonal as a square with a side length of 1 √ 2 will have a diagonal of 10 √ 2 and a square with a side length of 10 √ 2 will have a diagonal of 100 √ 2. Another use of the base is to show the silver ratio as its representation in base √ 2 is ...

For example, the base-8 numeral 23 8 contains two digits, "2" and "3", and with a base number (subscripted) "8". When converted to base-10, the 23 8 is equivalent to 19 10 , i.e. 23 8 = 19 10 . In our notation here, the subscript " 8 " of the numeral 23 8 is part of the numeral, but this may not always be the case.
Base32 is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).Since base32 is not very widely adopted, the question of notation—which characters to use to represent the 32 digits—is not as settled as in the case of more well-known numeral systems (such as hexadecimal), though RFCs and ...
Conversion of (357) 10 to binary notation results in (101100101) To convert from a base-10 integer to its base-2 (binary) equivalent, the number is divided by two. The remainder is the least-significant bit. The quotient is again divided by two; its remainder becomes the next least significant bit.
