The symbol # is known variously in English-speaking regions as the number sign, [1] hash, [2] or pound sign. [3] The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔. [4] In both the C and C++ preprocessors, as well as in other syntactically C-like languages, # is used to start a preprocessor directive. Inside macros, after #define, it is used for various purposes; for example, the double pound (hash) sign ## is used for token concatenation. ECMA-334 |C# language specification".

John Baugh, Robert Hass, Maxine H. Kingston, et al., "Octothorpe", The American Heritage Dictionary of the English Language (Boston: Houghton Mifflin, 2000) This is one of the recommended options to help you easily remember less than and greater than symbols. Well, you simply take the symbols as alligators, while numbers on either side are fish counts. Because the alligator always tries to eat fish, the number the mouth is open towards is always greater than. Writing Tips: How to Use the Hash Sign (#)". GetProofed. 6 February 2020.

Similarly, a less than symbol is placed between two numbers where the first number is less than the second number. An example for less than the inequality symbol is 5 < 10. It means that 5 is less than 10. We can offer discounts for long term hiring. Retailers for example use letter in their shop windows, and we are finding more and more professional musicians are hiring for their events.This symbol means that the number provided is less than or equal to the one on the left. Here is an example; 4 or 5 ≤ 4. In many scripting languages and data file formats, especially ones that originated on Unix, # introduces a comment that goes to the end of the line. [47] The combination #! at the start of an executable file is a " shebang", "hash-bang" or "pound-bang", used to tell the operating system which program to use to run the script (see magic number). This combination was chosen so it would be a comment in the scripting languages. The given statement is “April profit of Rs.150 was at least Rs.11 less than his March month profit” In computational complexity theory, #P denotes a complexity class of counting problems. The standard notation for this class uses the number sign symbol, not the sharp sign from music, but it is pronounced "sharp P". More generally, the number sign may be used to denote the class of counting problems associated with any class of search problems.

Less than or equal to—the number on the left is less than or equal to the number on the right; 2 or 3 ≤ 3 In lightweight markup languages, such as wikitext, # is often used to introduce numbered list items. At first only included capital letters and numbers , but in 1967 was added the lowercase letters and some control characters, forming what is known as US-ASCII, ie the characters 0 through 127. is greater than sign, it means that the value on the left side is greater than the value on the right side. Now we'll finally get to talk about why all these photos are of crocodiles. How to Remember Greater Than and Less Than SignsThe greater than symbol in maths is placed between two values in which the first number is greater than the second number. For example 10 > 5. Here 10 is greater than 5. The mouth is pointed at the 8, which means that 8 is more than 5. The sign always tells us the relationship between the first number and the second, so 5 < 8 can be translated to “5 is less than 8.” It works the other way, too. 1 ≤ 2 or 3 shows us a less than sign over half of an equal sign, so we know it means that 1 is less than or equal to 2 or 3.

Retrieved 24 November 2015.The greater than and the less symbols reduce the time complexity and it makes understanding easier. The ‘equal to’ sign is used to show the equality between two numbers or values. This sign contradicts both the greater than and less than sign. Even in terms of writing the equations, we use equal to sign. It is denoted by ‘=’. a b c Houston, Keith (2013-09-06). "The Ancient Roots of Punctuation". The New Yorker.

The alligator’s mouth is open toward the 4, so even if we weren’t sure that 4 is a bigger number than 3, the > sign would tell us. All inequality signs give us the relationship between the first number and the second, beginning with the first number, so 4 > 3 translates to “4 is greater than 3.”
