This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89
2. Denotes that a number is positive and is read as plus. Redundant, but sometimes used for emphasizing that a number is positive, specially when other numbers in the context are or may be negative; for example, +2. 3. Sometimes used instead of for a disjoint union of sets. − 1.
In the dot and line (or dot-dash) tally, dots represent counts from 1 to 4, lines 5 to 8, and diagonal lines 9 and 10. This method is commonly used in forestry and related fields. [ 6 ]
The number 10,000 is used to express an even larger approximate number, as in Hebrew רבבה r e vâvâh, [36] rendered into Greek as μυριάδες, and to English myriad. [37] Similar usage is found in the East Asian 萬 or 万 ( lit. 10,000; pinyin : wàn ), and the South Asian lakh ( lit. 100,000).
Another 100,000 observable universes filled with sand would be necessary to make a googol. [ 6 ] The decay time for a supermassive black hole of roughly 1 galaxy-mass (10 11 solar masses ) due to Hawking radiation is on the order of 10 100 years. [ 7 ]
Not all number systems can represent the same set of numbers; for example, Roman numerals cannot represent the number zero. Ideally, a numeral system will: Represent a useful set of numbers (e.g. all integers, or rational numbers) Give every number represented a unique representation (or at least a standard representation)
The statement that quantity f(x) depending on x "can be made" arbitrarily large, corresponds to ∀y : ∃x : f(x) ≥ y. arbitrary A shorthand for the universal quantifier. An arbitrary choice is one which is made unrestrictedly, or alternatively, a statement holds of an arbitrary element of a set if it holds of any element of that set.
