Consider that %f works with doubles and floats even though they're different sizes. stdargs has no way to warn printf which is used, so the compiler must be converting them to something consistent. So if double-precision works in printf at all, they're all being passed as doubles, and all being used as doubles, not floats.
All the implementations of printf that I have seen explicitly convert all floats to doubles in the code and do not leave it up to the compiler to decide whether to or not.
I have an assignment in which a character is the input of which some bits(from a position to certain position) are to be inverted (1's complement) and then the resultant character is to be returned....for example
unsigned char x = J from p = 3 to offset n = 5
01001010 inverted to... (1 Reply)

Hi All,
I have a matrix stored in a file matrix.mtx and looks like this:
1 0.5 0.33 0.25

J0(3) Linux Programmer's Manual J0(3)NAME
j0, j0f, j0l, j1, j1f, j1l, jn, jnf, jnl, y0, y0f, y0l, y1, y1f, y1l, yn, ynf, ynl - Bessel functions
SYNOPSIS
#include <math.h>
double j0(double x);
double j1(double x);
double jn(int n, double x);
double y0(double x);
double y1(double x);
double yn(int n, double x);
float j0f(float x);
float j1f(float x);
float jnf(int n, float x);
float y0f(float x);
float y1f(float x);
float ynf(int n, float x);
long double j0l(long double x);
long double j1l(long double x);
long double jnl(int n, long double x);
long double y0l(long double x);
long double y1l(long double x);
long double ynl(int n, long double x);
DESCRIPTION
The j0() and j1() functions return Bessel functions of x of the first kind of orders 0 and 1, respectively. The jn() function returns the
Bessel function of x of the first kind of order n.
The y0() and y1() functions return Bessel functions of x of the second kind of orders 0 and 1, respectively. The yn() function returns the
Bessel function of x of the second kind of order n.
For the functions y0(), y1() and yn(), the value of x must be positive. For negative values of x, these functions return -HUGE_VAL.
The j0f() etc. and j0l() etc. functions are versions that take and return float and long double values, respectively.
CONFORMING TO
The functions returning double conform to SVID 3, BSD 4.3, XPG4, POSIX 1003.1-2001. The other functions exist by analogy, and exist on sev-
eral platforms.
BUGS
There are errors of up to 2e-16 in the values returned by j0(), j1() and jn() for values of x between -8 and 8.
