[edit] Definition

FLOAT ln ( <FLOAT n> )

Returns the natural logarithm of number n (logarithm with base ε (Euler)).

[edit] Parameters

FLOAT n

- The number that will be used for the logarithm.

[edit] Returns

FLOAT : The natural logarithm of n.

[edit] Example

Import "log.dll";

Global
    float logarithm=0.0;
End

Process main()
Begin
    write_float(0,160,100,4,&logarithm);
	
    While(not(key(_ESC)))
	If (key(_1)) logarithm=ln(13.37); End 

        Frame;
    End
End

Used in example: import, write_float(), key(), ln()
