The simplest way to handle the whole problem is to use a table.

A table containing E3 to E192 ranges occupies 900 bytes.

A function which given a range and value returns the closest value (and the
next >= and =< values to allow simple iteration of a range in either
direction) occupies 540 bytes of 32bit Intel code.

It was never coded particularly for speed. On my 2GHz Athlon XP system it
finds around 2.6 million E96 values per second.
