formatted print

[whoami32]

Hi
I have a noob question wishing someone will explain this to me.
in a printf what does 10.5f mean?
could i get some examples?
Im doing assignment and i have example output
"%d %10.5f"
%
123 24.0 // bold as output.
suppose I have stack of numbers
123 <- top of stack
24

the assingment states
% is a formatted print taking a variable number of operands depending on the format string

thanks in advance

A floating-point numerical value with a f suffix denotes a float value. For example:

float float_value( 10.5f );
double double_value( 10.5 );

The f suffix basically tells the compiler that it's working with a float value.

In printf( )^[1], the first argument is the format string. This string holds the format data in which the string is printed.

so the number 10.5 is just a value? and any ideas on how this came about?

user inputs
"%d %10.5f"
%
123 24.0 // bold as output.

suppose I have stack of numbers
123 <- top of stack
24

Perhaps you should start by reading the relevant documentation. There's a lot you can do with printf.

Both 10.5f and 10.5 are both numbers. However, double has a greater precision than float. Compared to float, double has a larger size.
