As it says in the link I showed: The width field is a positive decimal integer controlling the maximum number of characters to be read for that field. No more than width characters are converted and stored at the corresponding argument. Fewer than width characters may be read if a whitespace character (space, tab, or newline) or a character that cannot be converted according to the given format occurs before width is reached.


So in your case you would code it as

double a;
sscanf_s("0.02", "%4f", &a);

since you have 4 characters in your string value. The number of digits after the decimal point is largely irrelevant for floats and doubles when reading in, it is only important when formatting for output. In general you are better off not specifying a width value as it can lead to loss of precision in input strings - unless your users all know exactly what format to use for their input data.
Just say 'NO' to evaluated arguments for diadic functions! Ash
