Antilog base e of a number (Float class)

Template:Float:AntilogE subtitle

These intrinsic functions return a number that is the natural anti-logarithm (or exponential) of the method object value.
The result is the natural logarithmic base (*e*) raised to the power of the method object value.

*AntiLog* and *AntiLogE* are synonyms.

Available as of version 7.3 of the `Sirius Mods`, the AntiLog function is
an object-oriented version of the $Exp function function.

## Syntax

%number = float:Antilog

%number = float:AntilogE

### Syntax terms

%value | A numeric variable to receive the antilog of the method object. |
---|---|

number | A Float value. |

## Usage notes

Although you might expect '**%x:log:antilog'**
to return the value in %x, the good fit techniques used
by the Log and AntiLog methods make the result not
quite exact, as shown in the following example:

2:log:antilog = 2.00000000023047 3:log:antilog = 3.00000000017113 4:log:antilog = 4.00000000047426 5:log:antilog = 5.00000000057644 6:log:antilog = 6.00000000069796 7:log:antilog = 7.00000000056701 8:log:antilog = 8.00000000047046 9:log:antilog = 9.0000000010268 10:log:antilog = 10.0000000005553

## Examples

The following statement returns '**1:antilog = 2.71828182845905'**.

PrintText {~} = {1:antilog}
