Hello,

I have an odd problem.  I need to use and simplify functions that have
been provided by a piece of software that insists on outputing the
functional results of a data mining proceedure, using "e" when
outputing numbers in scientific notation.

I'm having difficultly using Replace, Hold, etc. to correctly evaluate
these types of function formats.  For example, y = 5e+5x1+2e-1x2,
should be transcribed into 5 10^5 x1 + 0.2 x2.

Thanks,

Chuck
