Whats the symbol for exponent?

Question

You know when u type in alt and some numbers you get a symbol usually on the keyboard. for example, alt: 2024 is this Φ. What would the symbol for exponent be? alt: ?

Answer 1

As the first answerer said, there is a standard notation for exponents, which is to write a to the power of b as a^b. But I assume you want to type in those fancy exponent symbols like the pros do it, eh?

There are three exponent symbols that can be typed using standard alt-keycodes:

¹ = alt-0185
² = alt-0178
³ = alt-0179

There are actually superscript characters for every digit in unicode. For the digits 0, 4, 5, 6, 7, 8, 9, superscript n is at unicode 0×207n. Unfortunately, they are not on either code page 437 or windows 1252, which are the codepages that are referenced for the standard alt-codes (which is confusing, because a character's position on these codepages does NOT always match its unicode value). So you would have to use another method to input them.

Personally, I use the quick unicode input tool from cardbox, which enables input of arbitrary unicode characters by using the alt-number combination (and overrides the windows codepages). You can download the tool from http://www.cardbox.com/quick.htm . Then you can input every math symbol in unicode quickly by using the alt-number combination.

I should point out that once it's installed, alt-# will input the character with unicode value #, not the character # on code page 437 and/or windows 1252. So Φ will be input by alt-934, not alt-232 or alt-2024, for instance. √ is at unicode 8730. You can also input the code in hex instead of decimal - for instance, I can input ⁴ as either alt-8308 (since 2074 hex = 8308 dec) or alt-.2074 (the dot is very important, since it tells the program you're using the hex value). Also, if there's a character you want to input but whose unicode value you don't know, the shortcut alt-. will bring up the character map instantly so you can look it up (which is faster than having to dig through the start menu to find the character map).

Answer 4

Exponent...?

You can type Alt + 0178 for ², and Alt + 0179 for ³. The general symbol for an exponent, other than just writing the number as a superscript, is ^ and you don't need an Alt code for it. Just hit Shift + 6.

Answer 5

It means a random real number raised to a random power.
