integer/float input

[marlinde17]

I know I am overlooking something obvious, but I need to read from a binary file into integer and float variables. .read of course takes strings and I cannot get the >> operator to read only a specified amount of bytes. Any suggestion is appreciated.

Is your file in binary format or human-readable text format?

[marlinde17]

It is definitely not human-readable, it appears as a bunch of garbage characters. I t is in binary format.

Next question is, do you know what size each item is? In other words, is the file a list of float (single-precision) or long float (double precision)? And do you know the endianness of the file?

[marlinde17]

There are some of each size, but yes I do know which is which, where they are located in the file and the order in which they appear. I am not sure of the endianness, possibly middle-endian.

You should take a look through this thread

For floating point numbers, you'll have to use a union to put each byte in the proper spot.

Hope this helps.
