### Re: Need faster Exponentiate

Thanks paul doe, it is very fast but the approximation is not very good though it may be good enough for my needs.

### Re: Need faster Exponentiate

Here is a power approximation function that I found and converted: function powa1(byval a as double,byval b as double)as double dim as double rv,ln,am1 ln=log(a) am1=b-1.0 rv=a*ln*am1 ln*=ln am1*=am1 rv+=.5*a*ln*am1 rv+=a return rv end function I would like to convert this one to FreeBASIC https://m...

### Re: Need faster Exponentiate

Thanks dodicat, it is a noteworthy speed improvement for me.

I also found that using numbers like ^0.25, ^0.50, ^0.75, ^1.50 have almost no calculation cost with the standard Exponentiate function.

### Re: Fast uByte array to String routine

'fb_stralloctempdescf()' , because normally reserved to a FB internal use only, does not verify the following rule: Despite the use of the descriptor, an implicit NULL character (Chr(0)) is added to the end of the string, to allow passing them to functions in external libraries with...
