Discussion

The exp command returns the exponential function of an expression; that is, the number e raised to the expr power, where e is the base of the natural logarithm. The exp function returns infinite when the correct return value would overflow.

Note: Values returned by this command (a math function) are in real8 or 64-bit floating point precision. These values are displayed in the Command window rounded to 6 decimal digits. However, assignments and comparisons are performed on the full 64-bit value.

Example

Command input:

exp(1)

Result:

2.71828
