math, percentage

["Brian K. White" <brian@xxxxxxxxx>]

is there a way to do this with built in math instead of running bc ?

tp=`echo "scale=0;(${t}*100)/$T" |bc`

T = some dynamic total number like `ls |wc -l`
t = counter that starts at 1 and incriments as a loop walks through T
tp = percent of total job completed so far

Thanks
