Key Allen Wrench
What is a "hex" key on a scientific calculator or keyboard?
I am referring to the sentence, "To switch from scientific to logical display press the 'HEX' key. To switch back to scientific mode press the 'DEC' key twice. Return to calculator."
What does the "hex" key look like? Where is it, on the calc or on my keyboard?
I wiki'd the term "hex key" and only got back info about allen wrenches....wtf?
This page is no help to my particular question here, so I maybe can save you some time if you need to look it up which you probably dont, but if you do, dont look here...hehe;
http://en.wikipedia.org/wiki/Hex_key
I got the sentence containing the instruction to select the "hex key" from the calculator page at this site;

It comes from the calculator at;

Thank you in advance,

you seems to know about hex key more than you need..all you need is to know what is HEX
hexadecimal is a number system using 16 as it's base rather than the conventional decimal 10 base number system. There is another well known number system, binary which uses "2" as it's base
binary 0, 1
decimal 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
hexadecimal 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
number 11 in...
binary = 1011
decimal = 11
hexadecimal = B
=========
number 1223 in...
binary = 10011000111
decimal = 1223
hexadecimal = 4C7
*hexadecimal is yet another way of representing numbers
