Antilog and AntilogE (Float functions)

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 / AntilogE 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 / AntiLogE are object-oriented versions of the $Exp function.
• Available as of Sirius Mods Version 7.3.

Examples

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

   printText {~} = {1:antilog}
