En la versión del manual de Febrero 2005 salía en printf que:
Format:
The format takes the generic form %wt. n is optional and may be 1-9 to specify how many characters are to be outputted, or 01-09 to indicate leading zeros, or 1.1 to 9.9 for floating point. t is the type and may be one of the following:
c Character
s String or character
u Unsigned int
x Hex int (lower case)
X Hex int (upper case)
d Signed int
e Float in exponential format
f Float
Lx Hex long int (lower case)
LX Hex long int (upper case)
Lu Long unsigned int
Ld Long signed int
% Just a %
(Cambian también algunas definiciones, que he aprovechado en el copiar --> pegar)
En el manual de Noviembre 2005 aparecen los cambios:
The format takes the generic form %nt. n is optional and may be 1-9 to specify how many characters are to be outputted, or 01-09 to indicate leading zeros, or 1.1 to 9.9 for floating point and %w output. t is the type and may be one of the following:
c Character
s String or character
u Unsigned int
d Signed int
Lu Long unsigned int
Ld Long signed int
x Hex int (lower case)
X Hex int (upper case)
Lx Hex long int (lower case)
LX Hex long int (upper case)
f Float with truncated decimal
g Float with rounded decimal
e Float in exponential format
w Unsigned int with decimal place inserted. Specify two numbers for n. The first is a total field width. The second is the desired number of decimal places.
Yo entiendo que 1.1 to 9.9 for floating point significa 9 números máximo para la parte entera y 9 decimales máximo.
De todas formas támpoco lo tengo muy claro.
