- LIMIT (loexpr,expr,hiexpr)
-
- Returns value of 'expr' if 'expr' is greater than or equal to 'loexpr'
- and less than or equal to 'hiexpr'. Otherwise returns either 'loexpr'
- or 'hiexpr' depending on whether 'expr' is out of bounds low or high.
-
- That is, LIMIT keeps the value of 'expr' within the bounds given by
- 'loexpr' and 'hiexpr'.
