[edit] Definition

FLOAT log ( <FLOAT n> , [<FLOAT b>] )

Returns a logarithm of number n with base b. If b is not specified, the number 10 will be used as base.

[edit] Parameters

FLOAT n	- The number that will be used for the logarithm.
FLOAT base	- The base that will be used for the logarithm.

[edit] Returns

FLOAT : The 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=log(1000,9); End 
        If (key(_2)) logarithm=log(1000); End

        Frame;
    End
End

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