* WebGUI.str.sprintf ( formater, var1, var2, var3 )
|

|
||||
Formatter looks like:
|
||||
|
||||
%% - Returns a percent sign
|
||||
%b - Binary number
|
||||
%c - The character according to the ASCII value
|
||||
%d - Signed decimal number
|
||||
%f - Floating-point number
|
||||
%o - Octal number
|
||||
%s - String
|
||||
%x - Hexadecimal number (lowercase letters)
|
||||
%X - Hexadecimal number (uppercase letters)
|
||||
|
||||
Additional format values. These are placed between the % and the letter (example %.2f):
|
||||
|
||||
+ (Forces both + and - in front of numbers. By default, only negative numbers are marked)
|
||||
- (Left-justifies the variable value)
|
||||
0 zero will be used for padding the results to the right string size
|
||||
[0-9] (Specifies the minimum width held of to the variable value)
|
||||
.[0-9] (Specifies the number of decimal digits or maximum string length)
