Java; need help with math expressions (possible unicode problem)?

Question

Hi, I was wondering how to express the "line" that is often used in place of a division sign (such as a fraction). Can this be done with unicode? and if so, does it have an official name? Thanks in advance for any help!

Answer 1

The official Unicode division slash character is U+2215. See http://www.fileformat.info/info/unicode/char/2215/index.htm .



The official Unicode fraction slash character is U+2044. See http://www.fileformat.info/info/unicode/char/2044/index.htm .



The line in large vertical fractions can be created using U+2381 to draw a line beneath the numerator. See http://www.fileformat.info/info/unicode/char/2381/index.htm .



Or you might use instead U+0305 over the denominator. See http://www.fileformat.info/info/unicode/char/0304/index.htm .



Normally this kind of fraction building is done with higher protocols such as MTHML See http://www.w3.org/Math/ .



As to “i” in mathematics, usually it is just a normal Latin i in italics, like variables usually are. But see also U+2111 which is sometimes used to mean “imaginary part''.



The best site for identification of mathematical symbols is probably http://www.w3.org/TR/MathML2/chapter6.htm .

particular, you will desire to be stable at math...yet you do no longer would desire to be a math wizard. you will desire to understand incrementing, how variables are added, Boolean Ops, Logical Operators (AND, OR NOR, XOR, etc.), a thank you to apply a calculator (and coding a calculator is stable prepare ; ), a thank you to transform extensive kind bases (DEC to BIN or HEX or OCT), etc. the main significant component is to appreciate what the needed output is and the thank you to tell whether this is suited or incorrect. Coding in JAVA or C is unlike coding in assembly. maximum pc technological know-how and Programming books teach you a stable element of the mathematics you will desire to understand. And, it relies upon on the appliance...while you're making GPS application...uh, yeah, math is surprisingly significant...while you're making an app to save a Pokemon Card sequence in a database and only plugging factors at the same time...properly, math isn't this manner of massive deal. till you're writing all of it from scratch. the solid component and undesirable component approximately programming in 2006 in JAVA and C++/VC++ is a huge kind of the 'nuts and bolts' are already wrapped, acquire a type or a library, upload some application particular code...and voila! an app. Frankly, by using fact which you already know you have a concern w/ math, you will desire to concentration on development your math skilsl besides as your programming strengths. stable luck and achievement to you!!!

Answer 3

÷ The code is #247. To get it, hold down your ALT key, and type 0247 on the numeric keypad. It works typing it into Eclipse as a character, so you can put it in your text just like that.

Answer 4

do you mean a forward slash /
