1
00:00:00,800 --> 00:00:02,030
- [Narrator] Next let's take a look

2
00:00:02,030 --> 00:00:04,410
at some numeric formatting.

3
00:00:04,410 --> 00:00:07,530
Now, normally when you
display a positive number

4
00:00:07,530 --> 00:00:10,280
it's not preceded by a plus sign

5
00:00:10,280 --> 00:00:12,290
and when you display a negative number

6
00:00:12,290 --> 00:00:14,910
it is preceded by a minus sign.

7
00:00:14,910 --> 00:00:17,690
So let's take a look at how you can force

8
00:00:17,690 --> 00:00:21,500
a positive number to be
preceded by a plus sign.

9
00:00:21,500 --> 00:00:24,910
So here we have the
number 27 being formatted

10
00:00:24,910 --> 00:00:27,200
in a field of 10 as an integer

11
00:00:27,200 --> 00:00:29,850
by putting the plus sign
before the field width

12
00:00:29,850 --> 00:00:31,960
we're saying we would like it to always

13
00:00:31,960 --> 00:00:34,980
display a plus sign if in fact the value

14
00:00:34,980 --> 00:00:36,650
is a positive number.

15
00:00:36,650 --> 00:00:40,910
So in this case we get the
formatted string plus 27.

16
00:00:40,910 --> 00:00:45,260
Now, there is also a capability to fill in

17
00:00:45,260 --> 00:00:48,160
the extra spaces with a leading zero

18
00:00:48,160 --> 00:00:50,650
if that's something that
would be helpful for you,

19
00:00:50,650 --> 00:00:53,400
so in that case the leading zeroes

20
00:00:53,400 --> 00:00:56,840
would come in inbetween the
plus sign and the number,

21
00:00:56,840 --> 00:01:00,180
so as you can see here we've gone ahead,

22
00:01:00,180 --> 00:01:01,860
and actually we haven't done it yet,

23
00:01:01,860 --> 00:01:03,580
let's go ahead and do it, there we go,

24
00:01:03,580 --> 00:01:06,950
we've put in a zero before the 10d

25
00:01:06,950 --> 00:01:09,700
so this is two flags, plus and zero,

26
00:01:09,700 --> 00:01:13,010
and then a field width of 10 indicating

27
00:01:13,010 --> 00:01:16,100
that we're going to format an
integer in that field width.

28
00:01:16,100 --> 00:01:18,570
So in this case we'll get a plus sign,

29
00:01:18,570 --> 00:01:21,560
a bunch of zeroes, and then the number 27

30
00:01:21,560 --> 00:01:24,120
in our formatted result.

31
00:01:24,120 --> 00:01:27,020
You also have the ability to indicate

32
00:01:27,020 --> 00:01:29,590
that a space character should appear

33
00:01:29,590 --> 00:01:32,960
wherever the plus sign
would normally appear.

34
00:01:32,960 --> 00:01:35,540
So here we have a print statement

35
00:01:35,540 --> 00:01:39,000
that's going to display three
separate formatted values,

36
00:01:39,000 --> 00:01:42,100
the value 27 simply as an integer,

37
00:01:42,100 --> 00:01:44,700
the value 27 with a space character

38
00:01:44,700 --> 00:01:46,350
where the plus sign should go,

39
00:01:46,350 --> 00:01:49,680
and we're also going to show
you a negative 27 value,

40
00:01:49,680 --> 00:01:52,730
and we put in the space
here but that's not going to

41
00:01:52,730 --> 00:01:55,870
have an effect on the minus 27 value.

42
00:01:55,870 --> 00:01:57,990
So in the second case where we said

43
00:01:57,990 --> 00:02:01,120
to put in that space,
that's where the plus sign

44
00:02:01,120 --> 00:02:03,160
would normally appear if in fact

45
00:02:03,160 --> 00:02:06,700
we told it to display
one, and that enables us

46
00:02:06,700 --> 00:02:10,060
to basically align
these two numeric values

47
00:02:10,060 --> 00:02:12,540
in this particular case.

48
00:02:12,540 --> 00:02:15,180
Now, separately we have
seen this previously

49
00:02:15,180 --> 00:02:19,480
but I do want to iterate,
or revisit it rather,

50
00:02:19,480 --> 00:02:22,720
so here we're using the comma specifier

51
00:02:22,720 --> 00:02:25,020
which is for grouping digits,

52
00:02:25,020 --> 00:02:27,490
and in this case we're
formatting an integer

53
00:02:27,490 --> 00:02:30,600
with the thousands
separator, so you can see

54
00:02:30,600 --> 00:02:34,170
we get the last three digits, the comma,

55
00:02:34,170 --> 00:02:35,700
the next three digits, the comma,

56
00:02:35,700 --> 00:02:38,210
and the first two digits, and of course

57
00:02:38,210 --> 00:02:41,090
we can use that with floating
point values as well,

58
00:02:41,090 --> 00:02:44,210
so here we're formatting
a value with two digits

59
00:02:44,210 --> 00:02:45,530
to the right of the decimal point

60
00:02:45,530 --> 00:02:47,573
but we also have that comma flag

61
00:02:47,573 --> 00:02:50,493
to separate at the thousands.
