[Kind of a non-FreeBSD specific, /bin/sh question, but it also kind of
is, since the CL tools one might use vary from system to system.]

I want to compare two floating point numbers in a /bin/sh script. I
cannot seem to find an easy way to do so. The best I've come up with
is,

if awk "BEGIN { if ( $A < $B ) { exit 0 } else { exit 1 } }"; then ...

There's got to be a better way?
