decimal places

satee · Oct 15, 2003

Hi Everybody,
My program displays a variable of type float. How do I specify the number of decimal places?

Thanks for your help

printf("%.2f", someFloat);

#include <iomanip>;...cout << setprecision

;
// total number of digits before and after dec point.
Don't forget set to default (if you need).
See also setw

. See C++ i/o manipulators helps/docs.

Yes, old good unsafe printf is more, more better...
