ft_printf

Re-coded printf function

During this project I learnt about representation of floating point numbers in a computer and how printf function works.

Usage

make
gcc <file.c> libftprintf.a libft/libft.a -I libft/ -I ./

You are supposed to call ft_printf function from <file.c>. In order to get rid of warnings prototype:

#include "ft_printf.h"

at the top of <file.c>

Conversions and flags that has been managed in ft_printf:

• Conversions: s, p, d, i, o, u, x&c with flags:
• hh, h, l, ll.
• %%
• flags: #, 0, -, + & space
• minimum field-width
• precision

One more conversion as a bonus:

The b conversion prints out a binary representation of double and long double values. Works with the folowing flags:

• L - long double;
• z - prints sign;
• m - prints exponent;
• mm - prints mantissa;

Example

ft_printf("%Lb", LDBL_MAX);

will print:

0.111111111111110.111111111111111111111111111111111111111111111111111111111111111
