printf - Write formatted output
Synopsis
Description
printfformat[ argument ... ]
You can use printf to format and display output on standard output. The syntax is
similar to the ILE C/400 printf() function. printf formats using the following
conversion control string syntax:
%[flags][width].[precision]conversion
conversion specifies how the corresponding argument is displayed. You must
specify one of the following conversion characters:
v c Unsigned character.
v d Signed decimal number.
v e,E Scientific notation.
v f Floating point number.
v g,G Scientific notation with significant digits.
v i Signed decimal number.
v o Unsigned octal number.
v s String.
v u Unsigned decimal number.
v x Unsigned hexadecimal number with digits 0123456789abcdef.
v X Unsigned hexadecimal number with digits 0123456789ABCDEF.
flags control how the argument is displayed in the following ways:
v - Left justify arg within the field.
v + Prefix all numbers with a+or-.
v space Prefix all numbers with or -.
v 0 Pad field width with leading zeroes for d, e, E, f, g, or G.
v # Prefix octal numbers with 0.
v Prefix hexadecimal numbers with 0x for x or 0X for X.
v Display decimal point for e, E, f, g, or G.
v Display trailing zeroes for g or G.
width is the minimum number of character positions displayed. Using an asterisk (*)
character for the width means the value of the next argument is the field width.
The meaning of precision depends on the conversion character.
v d,i,o,u,x,X Precision specifies the minimum number of digits to be displayed.
v e,E,f Precision specifies the number of digits to be displayed after the decimal
point.
v g,G Precision specifies the maximum number of significant digits.
v s Precision specifies the maximum number of characters to be displayed.
