[avr-gcc-list] update on the last issue

[intiha Ho gai]

Hi,
I did a little bit more of search and figured that if i use the long
long for my X, Y coordinates and the sums, I should be able to handle
extremely large numbers. But now When i do that, it still give me
incorrect results. Even when i try to assign them those high values
directly, it fails!!!!

Here is my code. 

table.sumX = 12338578;
        table.sumY = -3336078;
        table.sumXSquared = 7260107358192; <-- 252
        table.sumXY = -1646741910392; <--- 253
         denom = ( table.n * table.sumXSquared - table.sumX * table.sumX);
         if (denom != 0)
                a = ( table.n * table.sumXY - table.sumY * table.sumX) / denom;
         b = (table.sumY - a * table.sumX) / table.n;
         
      sprintf(OutputMsg,"sumX=%ld, sumY=%ld, sumXY=%ld,
sumXSquared=%ld\r\n", 
table.sumX,table.sumY,table.sumXY,table.sumXSquared);
      UARTOutput(DBG_ERROR,"%s", &OutputMsg);
      sprintf(OutputMsg,"**************** A=%f     B=%f ***********\r\n",a,b);
      UARTOutput(DBG_ERROR,"%s", &OutputMsg);

This is the compile warning!
Cricket.c:252: warning: integer constant is too large for "long" type
Cricket.c:253: warning: integer constant is too large for "long" type
Cricket.c:259: warning: long int format, different type arg (arg 3)
<-- Why these warnings?
Cricket.c:259: warning: long int format, different type arg (arg 4)
<--It prints something wrong as well :(

where i have defined table as of type regTable (i know long long and
int64_t are the same but i am clutching at straws)

typedef struct regressTbl{
        int16_t n ;
        long long sumXY;
        int64_t sumX,sumY;
        long long sumXSquared;
}regTable;

Any ideas?

Thanks.
