Antilog base e of a number (Float class)

The `AntiLog` and `AntiLogE` 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.

## Syntax

%number = float:Antilog

%number = float:AntilogE

### Syntax terms

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

float | 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

`AntiLog`and`AntiLogE`are object-oriented versions of the`$Exp`function.- Available as of
`Sirius Mods`Version 7.3.

## Examples

The following statement returns `1:antilog = 2.71828182845905`

.

printText {~} = {1:antilog}
