converting binary to text in linux

I have a big bina开发者_高级运维ry file I have produced by writing an array of float numbers in binary format.

Now how can I simply convert that binary file to text ?

---

Use the UNIX od command, with the -t f4 option to read the file as 4 byte floating point values. The -A n option is also useful to avoid printing the file offsets. Here is the output of an example file that I created.

/tmp> od -A n -t f4 b.dump
        -999.876        -998.876        -997.876        -996.876
        -995.876        -994.876        -993.876        -992.876
        -991.876        -990.876        -989.876        -988.876
        -987.876        -986.876        -985.876        -984.876

You will need to reverse the process.

1. Read the file back into an array of floats.
2. Print the array use printf() or your favorite io function.

Any other approach will be ugly and painful; not to say this isn't ugly to start with.
