Code:
$ echo 123.4566 | bc -l | awk -F '.' '{ print $1; exit; }'
awk: syntax error near line 1
awk: bailing out near line 1

$ echo 123.4566 | bc -l | awk -F. '{ print $1 }'
123

And, of course, all you need is:

Code:
$ typeset -i n=123.4566;print $n
123

how to round it to near value....
if it is 123.999, then how to make it 124 using scripting in ksh

It seems you're using ksh88 (a Korn shell implementation that does not support floating point arithmetic).
So you can try something like this:
Code:
$ unset n
$ n=123.333                                                             
$ _n=${n#*.};((${_n%${_n#?}}>=5))&&print $((${n%.*}+1))||print ${n%.*}
123
$ n=123.666                                                             
$ _n=${n#*.};((${_n%${_n#?}}>=5))&&print $((${n%.*}+1))||print ${n%.*}
124
