E

E
is the exponential constant (base of natural logarithms), with numerical value .
  • Mathematical constant treated as numeric by NumericQ and as a constant by D.
  • E can be evaluated to any numerical precision using N.
E can be entered as Esc ee Esc (for "exponential e"):
Evaluate to any precision:
