You can enter intervals in round parentheses and in square parentheses.
However, round parentheses can be ambiguous, because (1-5) could be either an interval or an arithmetic operation with the result -4.You can express upper and lower limits in intervals using the following comparison operators:
Upper Limit
Option 1 |
Option 2 |
Option 3 |
Description |
> |
GT |
Greater than | |
>= |
=> |
GE |
Greater than or equal to |
Lower Limit
Option 1 |
Option 2 |
Option 3 |
Description |
< |
LT |
Less than | |
<= |
=< |
LE |
Less than or equal to |
Syntax for Entering Intervals
Use the expression IN to enter intervals:
LENGTH IN (5 - < 10)
from 10 to 5, such that 10 is part of the interval but 5 is not
LENGTH IN (5 - 10)
from 5 to 10, such that 5 and 10 are part of the interval
LENGTH IN (> 5 - < 10)
from 5 to 10, such that neither 5 nor 10 is part of the interval
LENGTH IN (> 5 - 10)
from 5 to 10, such that 10 is part of the interval but 5 is not
LENGTH IN (5 - 10, >20, 40)
All lengths from 5 to 10, greater than 20, or 40
