i be damned. now i don't know what to trust anymore.

hi,

can you plese tell me what the range of double is - for example like "8 bytes Real numbers with an approximate range of 4.19E-307 to 1.67E+308"

thanx

well your function will produce 0.0 with large numbers and that does make it unusable.
i maybe understanding a comment from above wrong, but i get the feeling, that NUMBER+E20 is the upper limit for calculations with purebasic. i am not expecting mathematica or a calculator, but when there are ...

i might not understand you but

help of purebasic : Double .d 8 bytes unlimited - and that means it should calculate. #

from a modula compiler help: LONGREAL 8 bytes Real numbers with an approximate range of 4.19E-307 to 1.67E+308 and an accuracy of about 16 decimal digits
and with function ...

yes it is - but it returns false results for large numbers:


1200.0 = Mod(3.528142089298538E20, 3732.0)
2872 = Mod(3.528142089298538E20, 3732.0) with a calculator
with the function


Procedure.d fmod(left.d, right.d)
Protected quota.q
quota = left - (right * (left/right))
ProcedureReturn quota ...

well, in calculations a number such as 352814208929853800000.0 results and the following function will not be able to calculate its correct value:


Procedure.d fmod(left.d, right.d)
Protected quota.q
quota = left - (right * (left/right))
ProcedureReturn quota
EndProcedure


the call to the ...

ssss.d = 352814208929853800000.0 <------- numerical overflow number to big
Double .d 8 bytes unlimited

this should work. it does work with modula-2, freepascal and c. for this reason i can not get an fmod to work.

thanx.

sorry, haven't be arround for longer time. the table failed with blobs and i think i fixed the problem. i added some stuff to read metadata, that i needed to write some schema data. probably the list with the meta data should be hashes - but it worked for this way. i post the whole thing again ...

thanx for your answer.
is there also something one can use that is not gnu. as i understand it, i could not sell my program anymore, if i use their dll's.

hi,

does anybody know how to make thumbnails from an existing pdf file without using adobe?
i am thinking of a free library such as libharu, purepdf etc.

thank you in advance
rko

more than one process will open a file and read and write it. i would ike to get something like share and un/lock region.

hi all,
is there anyway to do filelocking with pb? if not, is there some src for the win api that allows that?

thank in advance for any help.

i took liberty to add some stuff to your code. seems like the wrapper crashes on tables with a large number of columns and data.
does someone have some experience with that or even better a bugfix?

hi,

i am using 4.31 and seems like i am to stupid to make the examples (postings) work.

in this senenario the InitList's are ...

hi,
i see this for the first time. it nead. is there any chance that the methods be in the class? ex.:

Class(MemClass)
*mem1
*mem2
; Init memory

Method InitObject() ; <- NewObject calling InitObject
With *this
Debug "InitObject: AllocateMemory."
\mem1 = AllocateMemory(10*1024)
\mem2 ...
