   1e+38 "just happens" to be the largest representable floating point
   number in IEEE single precision (32 bit) floating point (and on both
   single and the most common double precision floating point on Vaxen).
   Many (most) C implementations use IEEE single to represent "float".

The maximum values will be changed to 1e307 (double precision) in the
next release of graph, part of `GNU Graphics'.  I've sent
mcmahon@owlnet a fix as well.

Testers are needed for the next release because we are adopting
`configure'.  Send me mail if you are interested in helping test the
next prerelease version.
