float values can b rounded off?

[sushant]

hi;

the code:

int main(void)
{
float i=6.10203;
printf("%d",i);
return 0;
}
is giving the o/p zero. why??????

 

[Richard Bos]

int main(void)
{
float i=6.10203;
printf("%d",i);
return 0;
}
is giving the o/p zero. why??????

Because you're lying to the compiler. Why should it magically figure out
which of the several possible interpretations of this undefined
behaviour you want?

the code:

int main(void)
{
float i=6.10203;
printf("%d",i);
return 0;
}
is giving the o/p zero. why??????

1. No proper indentation (stop using Google to post;
get a real NG client).
2. "I MUST NOT FORGET TO INCLUDE STDIO.H" - Homer (well, not really).
3. Ever heard of coercion?

printf("%d",i);

You're using the wrong conversion specifier in printf(). "%d" expects
an int argument. Use "%f" instead.

return 0;
}
is giving the o/p zero. why??????

Using the wrong conversion specifier leads to unpredictable results.

the code:

is giving the o/p zero. why??????

/* mha: After fixing
* 1) the failure to include <stdio.h>
* 2) the incorrect specifier for a floating-point argument, and
* 3) the failure to end the last line of output with an end-of-line
* character
* we get the working program below
*/
#include <stdio.h>

int main(void)
{
float i = 6.10203;
printf("%g\n", i);
return 0;
}

Screw ups:
1. Posting via google and losing all indentation. See sig.
2. Failure to #include <stdio.h>
3. Lying to the compiler about the type of i in the printf.
4. lack of blanks within the code (foolish style).

Either of 2 or 3 result in undefined behavior.

The result could be anything or nothing. The behavior
is undefined.

#include <stdio.h>

int main(void)
{
float i = 6.10203;
printf("%f\n", i);
return 0;
}

Tip: Prefer type 'double' over 'float'. It has
a much greater precision and range of values.

As well as excessive abbreviation. In the subject, it's "be" not "b".
In the body of the article, "output" is much clearer than "o/p".

I understand there's a common writing style that uses very short
abbreviations like "4" for "for", "2" for "to", and so forth. Please
don't use that style here in comp.lang.c.

Ahem. That's stdio.h, please. C is case-sensitive.

3. Ever heard of coercion?

Yes, but what has it to do with this code?

I think he conceived it while having ercion.

Ahem, ahem. That's <stdio.h> please.
C is spelling sensitive.

Well... it's either "I must not forget to #include <stdio.h>", or "I
must not forget to include stdio.h", IYAM.
