Can anyone specify the methods how to add decimal numbers in Linux

In what context? You mean from the shell? If so, `bc` would be my first choice, although `awk` can also to arithmetic.

Bash, and I assume any Korn oriented shell, cannot do floating point arithmetic. Almost any other programming environment can.

Hi.

Many shells can do integer arithmetic.

Versions of ksh of at least ksh 93s+ can do floating point arithmetic, see man ksh.

Also zsh, see post # 11, http://www.linuxquestions.org/questi...script-336772/

Best wishes ... cheers, makyo

to do calculation, use bc,dc , awk.

Or fire up Python, which has those capabilities (and much more, start by importing things from math):

Code:

python

I find it simpler than running an awk command every time I need to calculate something (less typing).

Edit: or if you're fine with typing, you could just

Code:

python -c 'print .2+.8'
