Hello,
I have a variable, TablePrecision, that specifies the precision of a number. How do i get printf to use that variable in its formatting without me having to hardcode it?
thanksCode:int TablePrecision = 2; double number = .839234; printf("%.2g", number); // put TablePrecision where the 2 is
Maybe
printf("%.*g", TablePrecision, number);
The manual page tells all.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
oh!
i thought it was only for white space. thanks, sorry for the stupid question.
