Looking for the massive text Formulae HP uses for their Equation Library in 50G/49G

[Tim Wessman]

I just checked the 48/50 source tree. They don't exist in there except in the "compressed" form as described and the utility to "convert" back and forth between them is long gone, but perhaps this will be helpful:

Code:

The following 1-byte values are used in equation
compression:

\01 CONST(
\02 UBASE(
\03 IFTE(
\04 COS(
\05 SIN(
\06 rad
\07 two
\08 2*
\09 )*
\0A This is passed through for line formatting
\0B 2-
\0C ^2
\0D /(
\0E =(
\0F ))
\10 *(

A little program, or even a bash script or something similar should be able to "reverse" the encoding without much trouble. Even manually search/replace shouldn't take long at all.
