WebMar 26, 2009 · I need to convert the float values to big-endian so that I can process the values. I know that straight swapping each byte with the adjacent byte doesn't work (especially since their floating point values). I've tried swapping them end for end (i.e., byte 15 from the file becomes byte 0 in my array) and that didn't work either. http://www.paulbourke.net/dataformats/reading/ tst feed co. ltd
