It kinda lives on in scanf's conversion specifier:

scanf("%lf", &double_var);

Formatting float without decimals topic

Hello,

Is it possible to format a float number, but without displaying decimals
if it is an integer ?

For example with "%.2f",
I get "10.50" for 10.5, but I would like "10" for 10 and not "10.00"

Thanks.
