General ⇒ Creating logarithm tables automatically

[dmuthu_cse]

Hello friends,

I need to create logirthm and antilogrithm tables. And is there any code to generate the logirthm and antilogrithm table automatically.

Expecting your suggestions and solutions.

Regards,
Muthu

Hi, Muthu

you could use the fp package (for floating point operations) and a loop (using the ifthen or multido packages, for example). A little example that calculates the natural logarithm of integer values 1<=t<=1000:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
\documentclass{article}
\usepackage{fp}
\usepackage{ifthen}
\setlength\parindent{0pt}
% the counter for the loop
\newcounter{mycount}
% the command that stores logarithms
\newcommand\natlogoft
\begin{document}
\whiledo{\value{mycount}<1000}
 {\stepcounter{mycount}\makebox[4em]{\themycount}% steps the counter and typesets the value of t
    \FPln{\natlogoft}{\themycount}\natlogoft\\}% calculates Ln(t) and typsets it
\end{document}
