#define EINA_DBL_EQ (   a,
  b 
)    (!!(fabs((double)(a) - (double)(b)) <= DBL_EPSILON))

Safe comparison of double.

Parameters:

[in]bSecond member to compare
Since (EFL) :
1.19
Returns:
true if two double match
Examples:
bg_example_03.c, edje-basic.c, evas-box.c, progressbar_example.c, and transit_example_03.c.
#define EINA_DBL_NONZERO (   a)    (!!(fpclassify((double)(a)) != FP_ZERO))

Determines if a double is not zero.

Parameters:
[in]aThe double
Returns:
true if double is not zero
Since (EFL) :
1.19
#define EINA_FLT_EQ (   a,
  b 
)    (!!(fabsf((float)(a) - (float)(b)) <= FLT_EPSILON))

[in]aFirst member to compare
[in]bSecond member to compare
Since (EFL) :
1.19
Returns:
true if two floats match
#define EINA_FLT_NONZERO (   a)    (!!(fpclassify((float)(a)) != FP_ZERO))

static Eina_Bool eina_dbl_exact ( double  a,
double  b 
) [static]

Warningless comparison of doubles using ==.

Parameters:
[in]aFirst member to compare
[in]bSecond member to compare
Returns:
true if two doubles match
Since (EFL) :
1.19
const char* eina_environment_home_get ( void  )

Returns the content of the environment referred by HOME on this system.

Returns:
A temporary string to the content referred by HOME on this system.
Note:
The result of this call is highly system dependent and you better use it instead of the naive getenv("HOME").
Since (EFL) :
1.15
Since :
3.0
const char* eina_environment_tmp_get ( void  )

Returns the content of the environment referred as TMPDIR on this system.

Returns:
A temporary string to the content referred by TMPDIR on this system.
Note:
The result of this call is highly system dependent and you better use it instead of the naive getenv("TMPDIR").
Since (EFL) :
1.15
Since :

static Eina_Bool eina_flt_exact ( float  a,
float  b 
) [static]

Warningless comparison of floats using ==.

Parameters:
[in]aFirst member to compare
[in]bSecond member to compare
Returns:
true if two floats match
Since (EFL) :
