Quote:All keyboard input will be interpreted when the input is completed, according to the modes set at that time.

This is also found on p. 74 of the manual v3.3.

So, when entering a real number featuring an exponent, we can test the exponent alone being smaller than 385 and greater than -384; this is already done now and takes care of cases 2 through 4 in Bit's post. Only case 1 remains to be taken care of; for that I tend to vote for "Shift the exponent so it becomes 84 to give the same result as if [+/-] was pressed first" for sake of consistency with other methods entering such a negative exponent (i.e. [EEX] [+/-] 384 or [EEX] 3 [+/-] 84 or [EEX] 38 [+/-] 4).

IMHO, that suggestion would cover all special cases Bit mentioned. And it stays consistent with the manual.

d:-)

This would still allow directly entering e.g. 1e-385 as 0.01e-383, which contradicts the rule "1e-383 is the smallest number that can be entered directly". I'm not suggesting it's a problem, just pointing it out. Is that what you want?
