Здравствуйте, помогите пожалуйста с этой функцией...
Справку читал, примеры смотрел, но всё равно не понятно из-за скромных познаний в русском языке.
Вот например, недавно встретившийся скрипт, точнее отрывок:
Код:
StringFormat('%06i\r\n', $i)

Единственное что я понимаю - шестёрка, но про её положение и прочее...
Фрагменты из справки:
Код:
Тип Тип переменной Формат выдачи 
d Integer Signed decimal integer. 
i Integer Signed decimal integer. 
o Integer Unsigned octal integer. 
u Integer Unsigned decimal integer. 
x Integer Unsigned hexidecimal integer, using "abcdef". 
X Integer Unsigned hexidecimal integer, using "ABCDEF". 
e Float Signed value having the form [ - ]d.dddd e [sign]ddd where d is a single decimal digit, dddd is one or more decimal digits, ddd is exactly three decimal digits, and sign is + or -. 
E Float Identical to the e format except that E rather than e introduces the exponent. 
f Float Signed value having the form [ - ]dddd.dddd, where dddd is one or more decimal digits. The number of digits before the decimal point depends on the magnitude of the number, and the number of digits after the decimal point depends on the requested precision. 
g Float Signed value printed in f or e format, whichever is more compact for the given value and precision. The e format is used only when the exponent of the value is less than -4 or greater than or equal to the precision argument. Trailing zeros are truncated, and the decimal point appears only if one or more digits follow it. 
G Float Identical to the g format, except that E, rather than e, introduces the exponent (where appropriate). 
s String String.
Код:
Flag Означает Стандарное значение 
- Left align the result within the given field width. Right align. 
+ Prefix the output value with a sign (+ or -) if the output value is of a signed type. Sign appears only for negative signed values (-). 
0 If width is prefixed with 0, zeros are added until the minimum width is reached. If 0 and - appear, the 0 is ignored. If 0 is specified with an integer format (i, u, x, X, o, d) the 0 is ignored. No padding. 
Blank Prefix the output value with a blank if the output value is signed and positive; the blank is ignored if both the blank and + flags appear. No blank appears. 
# When used with the o, x, or X format, the # flag prefixes any nonzero output value with 0, 0x, or 0X, respectively. No blank appears. 
# When used with the e, E, or f format, the # flag forces the output value to contain a decimal point in all cases. Decimal point appears only if digits follow it. 
# When used with the g or G format, the # flag forces the output value to contain a decimal point in all cases and prevents the truncation of trailing zeros.
Ignored when used with c, d, i, u, or s. Decimal point appears only if digits follow it. Trailing zeros are truncated.

Тип Означает Стандартное значение  
d, i, u, o, x, X The precision specifies the minimum number of digits to be printed. If the number of digits in the argument is less than precision, the output value is padded on the left with zeros. The value is not truncated when the number of digits exceeds precision. Default precision is 1.  
e, E The precision specifies the number of digits to be printed after the decimal point. The last printed digit is rounded. Default precision is 6; if precision is 0 or the period (.) appears without a number following it, no decimal point is printed.  
f  The precision value specifies the number of digits after the decimal point. If a decimal point appears, at least one digit appears before it. The value is rounded to the appropriate number of digits. Default precision is 6; if precision is 0, or if the period (.) appears without a number following it, no decimal point is printed.  
g, G The precision specifies the maximum number of significant digits printed. Six significant digits are printed, with any trailing zeros truncated.  
s The precision specifies the maximum number of characters to be printed. Characters in excess of precision are not printed. Characters are printed until a null character is encountered.

Въобщем, помогите разжевать(=

Поиграйся с StringFormat и всё станет ясно. Ничего сложного. :smile:
Код:
ConsoleWrite(StringFormat('%06i\r\n', 1))
ConsoleWrite(StringFormat('%6i\r\n', 1))
ConsoleWrite(StringFormat('%016i\r\n', 1))
ConsoleWrite(StringFormat('%16i\r\n', 1))
ConsoleWrite(StringFormat('%f\r\n', 1))
ConsoleWrite(StringFormat('%0.2f\r\n', 1))

Garrett, большое спасибо, как-то мысль поэкспериментировать обошла меня стороной(((=
