apologies if this is fixed in v0.4, but in in v0.3,
besides the error which caused Simon's problem,
there is the curious belief that expr(1) does FP
(floating point) math, or at least FP comparisons.
what `expr' is being assumed? no `expr' I know of,
including GNUs, knows anything about FP. what is
really happening is the `expr' line in question is
actually doing a string (lexicographic) comparison.
$ expr --version
expr (GNU coreutils) 5.2.1 [ ... ]
$ expr 1.2 + 3.4
expr: non-numeric argument
$ expr 1.2 == 1.2
1
$ expr 1.2 == 1.20
0
cheers!
