Uros Bizjak - has to include warnings about not drying animals in it
I have an older model with no such label therefore I am OK. ;)
--- Here is another program that demonstrates that there is some problem ---

Notice that "b" and "d" are different - there is no (equal or otherwise)
"conversion".
The operation of abs (according to printf output) seems to be:
If it is an integer accept and use it. If it is a float then it is = 0 .
Look what printf does to "i", thats an easy conversion.

#include <math.h>
#include <stdio.h>
int main ( ) {
/* float a, b, c, d, e, f, g, h, i, j; */ /* gives warning "argument x
has type 'double'", it */
double a, b, c, d, e, f, g, h, i, j; /* might be better to say type "float"
instead */
a = 16.000;
b = abs(a);
c = fabs(a);
d = abs((int)(a));
e = fabs((int)(a));
f = abs((float)(a));
g = fabs((float)(a));
h = (int)abs(a);
i = (float)abs(a);
j = 0.0;
printf("a = %.2f b = %.2f c = %.2f d = %.2f e = %.2f ", a, b, c, d, e);
printf("f = %.2f g = %.2f h = %.2f i = %.2f j = %.2f\n", f, g, h, i, j);
printf("a = %d b = %d c = %d d = %d e = %d ", a, b, c, d, e);
printf("f = %d g = %d h = %d i = %d j = %d\n", f, g, h, i, j);
return 0;
}
/* /usr/test/bin/gcc -Wall -Wconversion -o math_test_7 math_test_7.c */
/* Output:

*/
How can that be correct conversion ?
