Data types

[Froskoy]

Hi,

How many bytes of storage does a real data type require? I'm trying to predict the filesize of a rather large file.

Also, is an integer data type sufficient for storing values which will range from 747 to 1646 inclusive. If not, would it store values between -255 and 644?

Thanks very much,

Froskoy.

A real data type is 6 bytes, though you would do better to use a IEEE floating point data type in its stead (single, double, or extended) for numerous reasons. Though that alone won't dictate the size of a file containing it.

This will help answer your other (and others along the same lines) question:

Out of curiosity - why do you need to predict the file sizes? 2TB of storage is $200 these days. Memory requirements?

How many reasons STILL exist?

@dj - so just how much is a 2TB flash-drive these days?
