Yes. 12.340 has five significant digits. If you want to store it with
The maximum number you can store in a IEEE double is +infinity of course.
A 64 bit double has 52-bit mantissa, together with 1 sign bit it gives
you almost 16 decimal significant digits.
But like other things in life: It's not the size that maters, it's how

Yep , right , but how you *get* it by a beautiful code , that could be
really interesting.
Kinda of significance digit. For example:
A number `12.340' , and if say it has 2 digits' precision , then we
consider the `0' is not accurate , while `.34' is accurate.
So for a number stored in a double type , how accurate can it be ? (or
maybe how many bits in the fixed-point part is accurate)
Doesn't matter if it's unsigned or signed , some ...

Since you know the bit pattern that would yield the value, just make an
union with an uint64_t and a double, set the uint to the desired
bit-pattern, and printf the double:
#include <stdint.h>
#include <stdio.h>
int main(void)
{
union intdouble {
uint64_t foo;
double bar;
} maxdouble;
maxdouble.foo = 0x7FEFFFFFFFFFFFFF;
printf("%lf\n", maxdouble.bar);
return 0;
It depends on the exponent. If the exponent is ...

Hi,
how can i determine the maximum size of `double' without printing out
DOUBLE_MAX ?
And what about the precision of a `double' , anyone give a try ?
Google ain't giving much information , i just can't figure out , it's
very funny coding , isn't it ?

See:
Come on , just for fun , someone asks me if i could print out the
maximum number that can be stored in a double type , and the *precision*
of a double type.
For the first , maybe with some bit operations , no good idea from me.
And the second , well i tried to divide 2 by 3 , see when i reaches 7 (
should be 0.66....7 ) ,
may not a clever way.

Kinda off-topic for here but whatever...
Assuming 64-bit double, it has a mantissa of 52 bits and an exponent of
11 bits. If the mantissa is all-ones, that will give a significant of
2-2^(-52). The exponent cannot be all-ones (an all-ones exponent means
infinity or NaN), so the largest exponent is 2^11-2 = 2046, minus bias
(1023), it gives a maximum effective exponent of 1023, so that would
give a value of (2-2^(-52))*2^(1023) = 2^1024 - 2^971, roughly 10^308.
What do you mean by ...

Are the encapsulated packets being allowd through wanif OK? Remember
that the same packet will be IPv4 at some points, and IPv6 at others
depending which side of encapsulation they're at. You'll probably need
IPv4 rules on wanif and IPv6 rules on ip6if.
Have you used pflog to see if anything is being blocked?

Hello,
Could someone tell me why, given the following ruleset, I cannot get to my
machine from the outside on ipv6? Obviously, I just masked out the ipv6
address for security. Any insight would be much appreciated. Normally, I
am decent with pf when it comes to ipv4. But, I am utterly lost. Perhaps I
don't understand what the gif0 interface is truely doing. I know that I
have it configured to encapsulate IPv6 traffic in IPv4 but I don't know how
