## Todo
|
||
|
|
#### Implement %a correctly
|
||
|
|
#### Implement lenght modifiers Lqtjz
|

|
## Bugs
|
||
|
|
plus and space prints an extra space in rare undefined cases\
|
||
|
|
*floats lose precision*\
|
||
|
|
g printing 1.0000 while it should just print 1\
|
||
|
|
g giving the wrong return value in some cases\
|
||
|
|
e giving the wrong return value in some cases\
|
||
|
|
double check length modifiers "l" "ll" "h" "hh"\
|

## Usage
|
||
|
|
1. Simply clone or download the repository

|
## Tester
|
||
|
|
#### Todo
|
||
|
|
- check for -Wall -Werror -Wextra
|
||
|
|
- Add Infinity and NAN tests
|
||
|
|
- Harder checking on %n
|
||
|
|
- check with 2 conversions 1 correct and the other wrong?
|
||
|
|
- add strings with variables without any arguments
|
||
|
|
|
||
|
|
#### Usage
|
||
|
|
1. Download test.sh and the tests folder to your printf directory
|
||
|
|
2. Make the file executable `chmod +x test.sh`
|
||
|
|
3. Run `./test.sh` to start the test
