Convert number to scientific notation

[Joe Horn]

If you mean in a program, then the STRING function might suffice for you. WARNING: You must spell STRING in uppercase letters or it won't work as expected. For example:

STRING(10000,3,0) --> "1e4"

where the 3 argument means "Scientific Display Mode" and the 0 means "displaying zero digits after the decimal point". The built-in Help system contains more info (and lots more options) about the STRING function.
