3-72 Full Command and Function Reference
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 12-digit 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.
