''e'' is a constant on the TI-83 series calculators that holds the approximate value of [*http://mathworld.wolfram.com/e.html Euler's number], fairly important in calculus and other higher-level mathematics.<br />
<br />
The approximate value, to as many digits as stored in the calculator, is 2.718281828459...<br />
<br />
The main use of ''e'' is as the base of the exponential function [[TI-BASIC:E_Exponent|e^(]] (which is also a separate function on the calculator), and its inverse, the natural logarithm [[TI-BASIC:Ln|Ln(]]. From these functions, others such as the trigonometric functions (e.g. [[TI-BASIC:Sin|Sin(]]) and the hyperbolic functions (e.g. [[TI-BASIC:Sinh|Sinh(]]) can be defined. In [[TI-BASIC:Re_Thetai|re^θi]] mode, ''e'' is used in an alternate form of expressing complex numbers.<br />
<br />
Important as the number ''e'' is, nine times out of ten you won't need the constant itself when using your calculator, but rather the e^( and ln( functions.<br />
