HP 50g Graphing, 48gII Graphing manual Editb, Egcd

When evaluated, e returns its numerical representation if flag –2 or –3 is set; otherwise, e returns its symbolic representation.

The number returned for e is the closest approximation to 12digit accuracy. For exponentiation, use the expression 'EXP(x)' rather than e^x, since the function EXP uses a special algorithm to compute the exponential to greater accuracy. Even though the calculator often displays 'EXP(x)' as e^x, it’s still 'EXP(x)' internally.
