- c - Why does scanf () need %lf for doubles, when printf () is okay . . .
%f for float %lf for double %Lf for long double It just so happens that when arguments of type float are passed as variadic parameters, such arguments are implicitly converted to type double This is the reason why in printf format specifiers %f and %lf are equivalent and interchangeable In printf you can "cross-use" %lf with float or %f with
- Correct format specifier for double in printf - Stack Overflow
20 Format %lf is a perfectly correct printf format for double, exactly as you used it There's nothing wrong with your code Format %lf in printf was not supported in old (pre-C99) versions of C language, which created superficial "inconsistency" between format specifiers for double in printf and scanf

- 为什么double类型输入（scanf）用%lf，输出（printf）用%f?
%f是以float类型格式化输入或输出，%lf是long float的意思（估计是和%ld对应），也就是指double类型。 scanf读%f时，系统会按照4字节长度来读，读完要放到一个4字节的空间位置，也就是一个float所在的位置。 那么double有8字节空间，比4字节还大，能不能来放？
