# exp, exp1, exp2

```the exp of number the exp1 of number the exp2 of number ``` Values returned:
`exp `returns a number equal to the constant` e `raised to the power of` number`.
`exp1 `returns a number equal to 1 less than` e `raised to the power of` number`.

`exp2 `returns a number equal to 2 raised to the power of` number`.

Note:` e `` 2.7182818`

## Examples

```the exp of 1 --returns 2.718282 exp(1) exp1 of 1 --returns 1.718282 exp1(1) exp2 of 10 -- returns 1024 exp2 of 5 * 2 -- returns 64 exp2 of (5 * 2) -- returns 1024```

## Placeholders

number
An expression that evaluates to a number.

For example:

```169 / 19 pi (60.625 * 500) average(1,4,5,10) i+1 -- (where i is a number) line 1 of fld "Debits"```

Note: Formally, HyperCard distinguishes between factors (simple values) and expressions. The difference between factors and expression matters only if you like to drop parentheses. Most functions take factors as their parameters, which is why` abs of -10 + 2 `returns` 12 `and `abs of (-10 + 2) `returns` 8`. In short, always use parentheses to group things the way you want them to evaluate, and you won’t have to worry about the difference between factors and expressions.
