You need to typecast the variable in expression for precision.
[dpanwar@UnixServer1 NS]$ ns
% set a 18
18
% set b 1000
1000
% set x [expr double($a)/$b]
0.017999
To truncate the large float values, you may need to set the*
tcl_precision* variable
and get the desired result.
% set tcl_precision 10
10
% set x [expr double($a)/$b]
0.018

Subject: [ns] arithmatic in TCL for ns2
Hi ,
I have some problem regarding arithmatic expressions.
I have prepared a file .tcl and then I include it in main ns simulator
file.
For example,
set x [expr $a / $b]
ie.
x = 18 /1000 , it gives me zero value rather than 0.018. Why ?
what should I do Please? to get exact 0.018 .
Thanks you so much for your kind help.
Best Regards,
Imran Khan
