HELP PLEASE!!! CRAZY COMPILERS?????

[tguzella]

i need help: when i compile the following program (I have tested in bloodshed devc++, and visual c++ .net): --------------------------------------------------------------------------- #include #include #include #include using namespace std; int main() { float fnumber=1.123456789012345678; double dnumber=1.123456789012345678; long double ldnumber=1.123456789012345678; cout << "Float: " << fnumber << endl; cout << "Double: " << dnumber << endl; cout << "Long Double: " << ldnumber << endl; cout << "sizeof(float): " << sizeof(float) << endl; cout << "sizeof(double): " << sizeof(double) << endl; cout << "sizeof(long double): " << sizeof(long double) << endl; system("pause"); return 0; } ---------------------------------------------------------------------------- , the program outputs fnumber, dnumber and ldnumber (all of them) as 1.2346. i have no clue why this is happening... i am running this program on a athlon xp 2000+, under windows xp pro sp1... any help will be aprecciated...

the preprocessors are iostream, float.h, windows.h (i forgot about html tags on the forum...)

The default precision is the same for all floating-point types. Use the setprecision() manipulator or cout::precision() function to change the number of displayed digits.

You need to tell cout that you want to see more digits than the default (six I think) is:

[...]
long double ldnumber=1.123456789012345678;

cout.precision(20);
cout << "Float: " << fnumber << endl;
[...]
