[edit] Definition

FLOAT log2 ( <FLOAT n> )

Returns a logarithm of number n with base 2.

[edit] Parameters

FLOAT n

- The number that will be used for the logarithm.

[edit] Returns

FLOAT : The logarithm of n with base 2.

[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=log2(1024); End 

        Frame;
    End
End

Used in example: import, write_float(), key(), log2()
