Converts a java float into C float, when reading the data from a Java created file ( using the writeFloat function ).
float aFloat; unsigned char *pBytes; pBytes = (unsigned char * )&aFloat; pBytes[3] = _buffer[_offset++]; pBytes[2] = _buffer[_offset++]; pBytes[1] = _buffer[_offset++]; pBytes[0] = _buffer[_offset++]; return aFloat;
