Simple C: atof giving wrong value [migrated]
- by Doc
I have a program that reads input from a singe line(string obviously) and organizes it into arrays.
The problem I have is that at one point the program reads two different values and returns the first one twice. Initially I thought the program was reading the same value twice but when I tested it turned out that it got the correct one but is inputting the wrong one.
for example
Input: 2 0.90 0.75 0.7 0.65
sorry to snip it
(while(fgets (string[test], sizeof(string[test]),ifp))
pch = strtok_r(NULL, " ", &prog);
tem3 = atoi(pch);
while (loop<tem3)
{
pch=strtok_r(NULL," ",&prog);
venseatfloat[test][loop][DISCOUNT][OCCUPIED]=(float)atof(pch);
printf("%f is discount\t",venseatfloat[test][loop][DISCOUNT][OCCUPIED]);
pch=strtok_r(NULL, " ", &prog);
strcpy(temp, pch);
venseatfloat[test][loop][REGULAR][OCCUPIED]=(float)atof(pch);
printf("%s is the string but %.3f is regular\n", temp ,venseatfloat[test][loop][DISCOUNT][OCCUPIED]);
loop++;
}
output:
>0.900000 is discount 0.75 is the string but 0.900 is regular
>0.700000 is discount 0.65 is the string but 0.700 is regular
What is going on?
