Hi,
in my ksh script

expr 22 / 10 results as 2
but the actual result expected in 2.2.
how do i get that result. Please help

Thanks,

When using expr the '/' operation is not divide but returns the quotient. You need to use bc or something similar, for example:

Hi All,

i tried to assign it by the below way

$ test="scale=2;22/10" | bc
$ echo $test

but i got no output

please let me know ,why it is not getting assigned .. Am i wrong in anthing please let me know.

Thanks in Advance,
Arun

What you are doing here is assigning the 'standard output' of running '"scale=2;22/10" | bc' to the variable 'test'. Unfortunately that is not a valid command and the only output is to standard error. What you need is:

you can use this syntax also--

awk 'BEGIN{ print (22/10) }'
