Condensed notation for numerical data
Repetition
m∗a
m... counta... number
Example
3*0.3 → 0.3 0.3 0.3
Arithmetic sequence with difference ±1
a:b
a... first numberb... last number
Example
3:6 → 3 4 5 6
Example
8:5 → 8 7 6 5
Example
0.1:2.9 → 0.1 1.1 2.1
Arithmetic sequence with a given difference
m∗aDd
m... number counta... first numberd... difference
Example
4*0.5D0.1 → 0.5 0.6 0.7 0.8
Example
3*8D-2 → 8 6 4
Interval split by count
m∗a:b
m... number counta... first numberb... last number
Example
4*0.5:0.8 → 0.5 0.6 0.7 0.8
Example
3*8:4 → 8 6 4
Interval split by difference
a:bDd
a... first numberb... last numberd... difference
Example
2.9:3.1D0.1 → 2.9 3.0 3.1
Example
8.6:8.3D0.1 → 8.6 8.5 8.4 8.3
Example
3.0:3.5D0.2 → 3.0 3.25 3.5
Sequence repetition
In some groups of input data, a regular repetition of certain sequences of numbers can be observed, which can also be exploited. At the first occurrence, a sequence is defined by enclosing it in parentheses, which are written in the form =X, where X is any letter of the English alphabet with the exception of E and D. This letter is the identifier of the sequence and it is valid for the entire group, not the batch. The parentheses of sequences can overlap from the left as well as from the right.
Example
=A 3 2 =B 8 9 =C 7.23 =B =A =C
defines three sequences:
A → 3 2 8 9 7.23 B → 8 9 7.23 C → 7.23
At the next occurrence, the sequence is replaced by =X or =dX, where d is the difference by which the whole sequence will be increased.
Example
=G 0.3 0.8 =G 0.6 =G 1.5 =G → 0.3 0.8 0.6 0.3 0.8 1.5 0.3 0.8
Example
=G 0.3 0.8 =G 0.6 =2G 1.5 =0.2G → 0.3 0.8 0.6 2.3 2.8 1.5 0.5 1.0
If a sequence is repeated back-to-back several times, it may be written in the form m*(sequence), where m is the sequence repetition count. For a sequence enclosed by the parentheses, it is possible to use all of the condensed notations described above.
Example
3*(4 3) → 4 3 4 3 4 3
Example
2*(=A 4 3 =A =2A) → 4 3 6 5 4 3 6 5
