## NAME

```       ggidev-sign_3, ggidev-bits_3, ggidev-eq0_3, ggidev-gt0_3, ggidev-ge0_3,
ggidev-lt0_3, ggidev-le0_3 - triple-int properties

```

## SYNOPSIS

```       #include <ggi/internal/triple-int.h>

int sign_3(unsigned x);

int bits_3(unsigned x);

int eq0_3(unsigned x);
int gt0_3(unsigned x);
int ge0_3(unsigned x);
int lt0_3(unsigned x);
int le0_3(unsigned x);

```

## DESCRIPTION

```       sign_3 checks the sign of x.

bits_3 counts the number of significant bits of x. I.e.  leading  zeros
in  a  positive  value  and  leading  ones  in a negative value are not
counted.

eq0_3, gt0_3, ge0_3, lt0_3 and le0_3 tests the relation between  x  and
zero.  eq0_3  tests  if  x is equal to zero, gt0_3 if x is greater than
zero, ge0_3 if x is greater than or equal to zero, lt0_3 if x  is  less
than zero and last but not least le0_3 tests if x is less than or equal
to zero.

```

## RETURNVALUE

```       sign_3 returns -1 for negative values, 0 for  zero  values  and  1  for
positive values.

bits_3  returns  0 for x equal to 0 or -1, 1 for x equal to 1 and -2, 2
for x equal to 2, 3, -3 and -4 etc.

eq0_3, gt0_3, ge0_3, lt0_3  and  le0_3  all  returns  non-zero  if  the
relation is true, and zero otherwise.

```

## EXAMPLES

```       Some triple-int tests:

unsigned x;

assign_int_3(x, 5);
ASSERT(sign_3(x) == 1);
ASSERT(bits_3(x) == 3);
ASSERT(!eq0_3(x));
ASSERT(gt0_3(x));
ASSERT(ge0_3(x));
ASSERT(!lt0_3(x));
ASSERT(!le0_3(x));

```
