Some keywords are expecting percentage range specifications. A percentage range specification consists either of only one percentage value, which must start with an comparative operator, or with two percentage values, separated by whitespace (and without comparative operators).
If a percentage range specification consists of only one value, this value is denoting the range, otherwise both values will specify the range, with a lower and an upper bound.
The percentage value is a positive integer between zero and 100 (inclusive). This value must be suffixed with a percentage symboi.
These are the permissible comparative operators:
> | More than | |
>= | At least | |
< | Less than | |
<= | At most |
The following examples are percentage ranges for counting connected pawns on the board.
>70%
More than 70% of all pawns on the board are connected.
>=20%
At least 20% of all pawns are connected.
30% 70%
Between 30 and 70% (both boundaries are inclusive) of all pawns on the board are connected.
