) |
| (!!(fabsf((float)(a) - (float)(b)) <= FLT_EPSILON)) |
Safe comparison of float.
- Parameters

| [in] | b | Second member to compare |
- Since
- 1.19
- Returns
true if two floats match
◆ EINA_FLT_NONZERO
| #define EINA_FLT_NONZERO |

◆ eina_environment_home_get()
| 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
