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
