Where can I find a site for math expressions?

[xanatose]

I need it as a reference.  (both to read formulas and to express formulas).

For a trivial example: How do you that write that you only want the integer part of x/y?

int c that would be (int)(x/y). But I do not know how to write it when writing a math equation.

If you have a c code ,you have also the asm code.
Add /FA in the command line of the c++ compiler and you get an asm file.

For your example it depends on what you mean by "integer part".

There is an incomplete listing here:

Thanks everyone.

@MichaelW Thanks for the link.
Is interesting to know there are different symbols for floor, ceil and round.

(int)(x/y) is the same as floor(x/y) except no function call.


A pity that the table only shows the result of the html and latex symbols. But not the way to write it neither on HTML nor on latex. Neither does it show the Unicode symbol.

Hi xanatose,

A pity that the table only shows the result of the html and latex symbols. But not the way to write it neither on HTML nor on latex. Neither does it show the Unicode symbol.

which symbols would you like to write it with Latex?

They're represented in HTML simply as Unicode characters.

For a list of Unicode characters, see the "Mathematical Symbols" section: http://www.unicode.org/charts/#symbols (specifically, Mathematical Operators:Floors and Ceilings).

For LaTeX, this covers everything you'll probably need: http://en.wikibooks.org/wiki/LaTeX/Mathematics

Hi Tedd,

For LaTeX, this covers everything you'll probably need: http://en.wikibooks.org/wiki/LaTeX/Mathematics

the list gives a good overview, but isn't complete. Thank you.

the list gives a good overview, but isn't complete. Thank you.

1. I didn't say it was complete, but "covers everything you'll probably need" -- specifically, for xanatose.
2. There's more.. http://en.wikibooks.org/wiki/LaTeX/Advanced_Mathematics
3. There will never be a complete list. There are far more additional packages than any single reference can document, and there's always the possibility of creating more symbols and notations for yet another newly invented obscure branch of mathematics.

A Soluce is never complete.
