I'm using DJGPP/RHIDE and am producing what appears to me a strange
result when printing a float variable. After assigning a value and
calling printf to display the result:

profit = 2150.48;
printf("Profit $%f\n", profit);

it produces:

Profit: $2150.479980

Of course I learned that printf displays a floating point variable
with six digits after the decimal point by default. Why though does it
print out .479980 instead of .480000? I'm guessing that its a setting
within DJGPP/RHIDE that is set at default to produce this output but I
have had no luck finding where to change this. Or is this a C issue
rather than compiler specific? Would appreciate any help shedding some
light on this matter.

Thanks,

Andy
