Question 1:

If, for example, I have a sequence n=1,2,3, 5.... and I have to divide this sequence by 2, that is n/2=0.5, 1, 1.5, 2, 2.5...., but in my next formula I have to use only whole parts of the results: n/2(whole)= 0, 1, 1, 2, 2,...

 

Is there a mathematical symbol for such expression ? I tried few web sites, including the Wikipedia, but was not able to find one.

 

Question 2:

Is there mathematical symbol for rounded numbers?

 

Please, help !

Question 2:

• The largest integer that is less than or equal to [math]x[/math]: [math]\lfloor x \rfloor[/math]
   
   
  
• The smallest integer that is greater than or equal to [math]x[/math]: [math]\lceil x \rceil[/math]

 

Question 1:

• The sequence [math]\langle 0,1,1,2,2,...\rangle[/math]: [math]\langle\,\lfloor n/2 \rfloor:n\in\langle 0,1,2\cdots\rangle\,\rangle[/math]

Thank you very much !

 

Where can I find all Math symbols, along with the examples?

Is there an Internet site that has them?

The names of those funny little symbols that D H posted are the floor and ceiling functions.

Thank you very much !

A list of such symbols, together with the ascii and html representations can be found at

That is nice. Thanks. Unfortunately, not all symbols are there. The symbols for ceiling and floor functions that I need are not included on that web page. I used floor(n/2) for now, but would like to change to the symbol one day.

 

Is there HTML code for floor and ceiling functionn symbols?
