Anyone know of a good C library that efficiently implements conversion from
a processor-native 'double' floating-point precision number to some standard
form of an 8-bit floating-point number and back? And a Perl5 library to go
with it?
An array of a million small real numbers could be stored in a one-megabyte
file on disk and then memory-mapped and shared by multiple processes as a
way of doing ultra-efficient lookups of document-specific weight factors.

| (...) Hmm, 8 bit floating point numbers can't implement a very large range of numbers. How many bits of exponent were you planning on? I think conversion would probably actually be pretty easy since you will just take e bits of the exponent from the (...) (24 years ago, 3-Jan-01, to lugnet.off-topic.geek)
