| Comment | A perfect every-day calculator with a versatile
programming
model! Very balanced feature set without any shortcomings worth
mentioning.
Stephen J. Thomas reports a bug which cannot be reproduced on either of
my
units:
If you are entering a number with a decimal
point,
and then use the back-arrow key to erase any (and all) digits
to the right of the decimal point AND erase the decimal point, the
magnitude
of the integer portion of the number will be incremented by 1 when the
ENTER
key is pressed. Found on 2750A15169
(1987/50).
Also reported on a 2222A02450 (1982/22) by Joe Edwards.
