 		 #165348 - double = double precision float
Responding to: ???'s previous message
Erik Malund said:
you can not store non-integers in a double

A double is not a DWORD.

A double is the standard C data type expected to be a double-precision floating-point number. In some implementations (Such as Keil C51) treated the same as a float, i.e. no extended range and resolution.

Hence, a double is specifically intended for non-integer numeric values.

the '51 is excruciatingly slow in handling double, double indxsing.

If we ignore the above mistake about the double data type, we can say: A '51 is excruciatingly slow at handling multi-dimensional arrays. Especially if the indices are larger than 8 bits.

Edit: Fixed spelling error.

                                          double = double precision float            01/01/70 00:00      
                                             not used it after seeing the effects, thus            01/01/70 00:00      
                                                Good incentive to look at fixed point            01/01/70 00:00      
                           Please explain            01/01/70 00:00      
               But Why Keil??            01/01/70 00:00      
         two dimensional input provided at the ports            01/01/70 00:00      
            simulate the data.            01/01/70 00:00      
               seems that not the real MCU            01/01/70 00:00      
                  to jacksonc ben            01/01/70 00:00      
                     The serial port don't need to know what you transfer            01/01/70 00:00      
   this is obviously not for an embedded app.            01/01/70 00:00
