This means that floating point data written on one machine may not be readable on. little endian. The fast, easy, shareable online calculator. Shifting deals with the logical issues of high order or low order of bits, not where they are physically located in memory, so left-shifting by 16 bits is going to multiply the value by 2^16 (assuming the data type is big enough to contain that result) regardless of endianness. The data values > going in to the fortran code are sensible, but the netcdf output is quite > wonky. Because there are many floating point formats, and a lack of a standard "network" representation, no standard for transferring floating point values has been made. Below we consider the right most byte is the least significant. You can use a calculator. The output CSV header row is optional and you can force double quotes around each field value.
