digits are valid digits, and the decimal 6 bits.For double-precision numbers, when using the%LF format character output, the first 16 digits are valid digits, and the decimal 6 bits.The format for M.N can also be represented as follows (example)Char ch[20];printf ("%*.*s\n", m,n,ch);The front of the * defines the total width, and the back defines the number of outputs. corresponding to the outer parameters m and n respectively. I think the benefit of this approach is that you can assign values
