## Numbers
Numbers can be integer and floating point, which are usually not distinct.
(but bitwise operations can only use integers)
The integer part can represent a signed 64-bit, and the fraction part in floating point can represent up to 16 digits.
Numerical values can be expressed in follows.
Only decimal numbers can have fraction part.
Type | Representation of '1234'
------------|-------------------
Decimal | 1234, 1234.0
Hexadecimal | 0x04d2, 0x4D2
Octal | 0o2322
Binary | 0b0000010011010010
## DateTime and TimeSpan
DateTime and TimeSpan describe as quoted string.
Double quotes (`"`) or single quotes (`'`) can be used as the quotation mark.
### DateTime
DateTime represents a point on the timeline.
```
----------x----------> Passage of time
^
DateTime
```
There are following types of specification methods.
1. [General style](#DateTime---General-style)
2. [Standard style](#DateTime---Standard-style)
3. [Week number style](#DateTime---Week-number-style)
#### DateTime - General style
This is a general notation with separated by a slash and colons.
The year and date part can be omitted, in which case the current year/day will be used.
Input | Result
----------------------|----------------------
'2019/8/18 7:36:13' | '2019/08/18 07:36:13'

#### DateTime - Week number style
Specify the date by the week number of the year.
'CW01' is the week with the year's first Thursday in it.
The fraction part represents the day of week, begening at 1:Monday and ending at 7:Sunday.
If the year part is omitted, the current year will be used.

### TimeSpan
TimeSpan represents the length between two points on the timeline.
TimeSpan can be negative value.
```

(Positive) (Negative)
```
There are following types of specification methods.
1. [Comma separated style](#TimeSpan---Comma-separated-style)
2. [Unit specified style](#TimeSpan---Unit-specified-style)
#### TimeSpan - Coron separated style
This style must start with a sign (+/-).
