Alignment arithmetic operations

Description:

Perform alignment arithmetic operations between two sequences.

Syntax:

 

A??B

 

A??x

 

x??A

x is parsed as a sequence whose members are x and having same length as sequence A

Note:

Alignment Arithmetic Operations are performed between two sequences of same length. ?? is the alignment operator, which can be ++ (alignment addition), -- (alignment subtraction), ** (alignment multiplication), // (alignment division), %% (mode operation) and \\ (integer division).

Parameter:

A

A sequence

B

A sequence

x

A real number

Return value:

Sequence

Example:

 

A

 

1

=[4,2,3,3]++[5,10,2,1]

Perform alignment addition on two sequences; the computing process is  [4+5,2+10,3+3,3+1] amd result is [9,12,5,4]

2

=[4,2,3,3]--[5,10,2,1]

[-1,-8,1,2]

3

=[4,2,3,3]**[5,10,2,1]

[20,20,6,3]

4

=[4,2,3,3]//[5,10,2,1]

[0.8,0,2,1.5,3.0]

5

=[7,12,3,3]%%[5,10,2,1]

[2,2,1,0]

6

=[7,12,3,3]\\[5,10,2,1]

[1,1,1,3]

 

Alignment arithmetic operations between a sequence and a real number

 

A

 

1

=[70,120,30,30]**0.1

Perform alignment multiplication between a sequence and a real number; the computing process is [70*0.1,120*0.1,30*0.1, 30*0.1] and result is [7,12,3,3]

2

=80\\[10,5,4,20]

[8,16,20,4]
