ios::hex Format numeric values as base 16 (hexadecimal).
ios::showbase Display numeric constants in a format that can be read by the C++ compiler.
ios::showpoint Show decimal point and trailing zeros for floating-point values.
ios::uppercase Display uppercase A through F for hexadecimal values and E for scientific values.
ios::showpos Show plus signs (+) for positive values.
ios::scientific Display floating-point numbers in scientific format.
