Array of 6 million doubles

[stavrospapa]

Dear Devs,

(it may sound crazy)
Need to create dynamically an array of 6 million double numbers
that will be loaded from a resource file, so that to keep the exe small.

I went thru the posts, still need a good starting tip on how
to approach this issue.

thanks!

On double you probably mean TReal, a 64-bit (8-byte) number. 6 million is around 6 "mega", 6*8=48, so you would need around 48 megabytes of memory for that. Most current devices do not have such amount of free memory.
Otherwise you can either use TPckg/Buf<TReal>+RFile::Read or RFileReadStream::ReadReal64L for reading TReal-s from files.

well if the program logic premits, instead of reading the entire array... it would be a better idea to read a portion and work on it and keep the array always sorted....

other wise this is mostly impossible, as to get so much heap...
