I want to read/write C float values from a binary file if it was created in C?
The file was created like this:
#include <stdio.h>
int main() {
const int NUMBEROFTESTELEMENTS = 10;
/* Create the file */
float x = 1.1;
FILE *fh = fopen ("file.bin", "wb");
if (fh != NULL) {
for (int i = 0; i < NUMBEROFTESTELEMENTS; ++i)
{
x = 1.1*i;
fwrite (&x,1, sizeof (x), fh);
printf("%f\n", x);
}
fclose (fh);
}
return 0;
}
I found a method like this:
file=open("array.bin","rb")
number=list(file.read(3))
print (number)
file.close()
But this won't guarantee to me the read value was a C float.
mch :
import struct\nwith open("array.bin","rb") as file:\n numbers = struct.unpack('f'*10, file.read(4*10))\nprint (numbers)\n\nThis should do the job. numbers is a tuple of the 10 values.",
