I have a customer that is insisting on 'double' floating point and a PIC(48
or 64 bits). Having just recently converted 6801 fp routines to 68HC05 fp
routines I know it takes a fair bit of code.
Do you have an FP libary for PIC or can you give me a statement that I can
use to convince the customer that they are 'pushing it'. Or, should I
convert the 68HC05 routines? 8-(

64 bits! Check out this month's issue of Embedded Systems Programming.
Jack Crenshaw writes an article about floating point arithmetic
(specificially about multiplication) in which he notes:
"With a 64-bit counter, we can span the solar system to an
accuracy of one wavelength of light."
Perhaps this is the resolution your customer seeks.
