On the 64 bit linux version only the least significand 32 bits are correct. This happens because the C function that is used to implement freadi uses int* instead of long*. I have fixed this in the source code. >Is this a known problem? Any suggestions on how to fix this or work around it? If 32 bit numbers are sufficient, shift the result 32 bits to the left and then 32 bits to the right, or if it is unsigned, 'bitand' with 0xffffffff. If you need more bits, you can implement freadi using freadc.
