Vts Posted July 24, 2008 Share Posted July 24, 2008 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 ! Link to comment Share on other sites More sharing options...

Vts Posted July 27, 2008 Author Share Posted July 27, 2008 Thank you very much ! Where can I find all Math symbols, along with the examples? Is there an Internet site that has them? Link to comment Share on other sites More sharing options...
the tree Posted July 27, 2008 Share Posted July 27, 2008 The names of those funny little symbols that D H posted are the floor and ceiling functions. Link to comment Share on other sites More sharing options...
Country Boy Posted July 29, 2008 Share Posted July 29, 2008 Thank you very much ! Where can I find all Math symbols, along with the examples? Is there an Internet site that has them? A list of such symbols, together with the ascii and html representations can be found at http://www.barzilai.org/math_sym.htm Link to comment Share on other sites More sharing options...
Vts Posted August 3, 2008 Author Share Posted August 3, 2008 A list of such symbols, together with the ascii and html representations can be found athttp://www.barzilai.org/math_sym.htm 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? Link to comment Share on other sites More sharing options...
