easy C shell math calculators

alias calc 'echo "scale=4;\!*"|bc -l'; alias xcalc 'echo "\!*"|bc -l'
allows simple C shell access to the power of bc - never could figure out how to do the same thing with Bash - that's why I use tcsh most of the time.
Sample Output
$ calc 5*8.43
$ set pi=`xcalc 4*a(1)` ; echo $pi
# note error in last digit - should be 6 according to 
# http://www.greatplay.net/uselessia/articles/pi2-100.html
$ set h=20; set r=17.2 ; set v=`calc $pi*$h*$r^2`; echo $v
$ calc 7.2*(18.2+3.98-2.04)
$ echo `calc 7/22` or `xcalc 7/22`
.3181 or .3181818181
