There don't half seem to be some puzzling things going on in TOS206. Someone must have fiddled with all this at some point in the past.

Code: Select all

#if TOSVERSION < 0x200
        bsr.s     hardsee1
#else
        bsr       hardsee1
#endif

Chucked the Falcon my desk and got a H4 out to test the new TOS patches. Basically it made no wards other than I think STram test was about 4 seconds quicker.

#if TOSVERSION < 0x200
        bsr.s     hardsee1
#else
        bsr       hardsee1
#endif

The first version is as shorter, smaller command than the second. But it can only work if the called routine is close enough (within 127 bytes each way). I infer TOS 2 and above have extra code between this command and the called routine meaning the longer, slower, plain bsr has to be used.

Didn't want to further contaminate @ijor's blitter thread with GB6 stuff.

So I have been messing about with the GB6 code for the past several hours. Long and short of it is that Hisoft Basic simply rounded down The divisions all the time. For example.

Code: Select all

 21861         21860         100 
 21861         21861         100 
 21861         21862         99 
 21861         21863         99 
 21861         21864         99 
 21861         21865         99 
 21861         21866         99 
 21861         21867         99 
 21861         21868         99 
 21861         21869         99 
 21861         21870         99 

Where the first 99 should have been

Code: Select all

21861 * 100 \ 21862 = 99.9954258530784

But no matter what I did it would simply refuse to output the decimal places. But if I actually added 0.5 onto the end it would actually print 99.5.

So anyway long story short there seems to be two operators according to the manual and it does not really explain either one.

So:

Code: Select all

21861 * 100 \ 21862 = 99

Code: Select all

21861 * 100 / 21862 = 99.9954258530784

The actual new test table is now:

Code: Select all

 21861         21860         100.0045745654162 
 21861         21861         100 
 21861         21862         99.99542585307844 
 21861         21863         99.9908521245941 
 21861         21864         99.98627881448956 
 21861         21865         99.9817059227075 
 21861         21866         99.97713344919052 
 21861         21867         99.97256139388122 
 21861         21868         99.96798975672216 
 21861         21869         99.96341853765602 
 21861         21870         99.9588477366255 

So next I just need to round "UP" so then those 99% scores should not be so prominent then.

[ijor]

That was exactly what I was going to reply to your PM. You were using the wrong division operator. The so called back slash division is an integer division. So you were truncating twice by mistake.

Glad now it is solved

[exxos]

Never knew there was 2 operators for division

Anyway, using CINT which does the rounding. New results are now :

(100% exactly is half way down the list)
