Examples
-- Rounding functions, using multiples of the second argument -- -- FLOOR returns the smaller multiple -- MROUND returns the nearer multiple (does not work with negative values) -- CEILING returns the larger multiple -- ISO.CEILING is like CEILING, handles differently negative numbers DEFINE VAR Vals = GENERATESERIES ( 5, 20, 2 ) EVALUATE ADDCOLUMNS ( Vals, "FLOOR", FLOOR ( [Value], 3 ), "MROUND", MROUND ( [Value], 3 ), "CEILING", CEILING ( [Value], 3 ), "ISO.CEILING", ISO.CEILING ( [Value], 3 ) )
Value | FLOOR | MROUND | CEILING | ISO.CEILING |
---|---|---|---|---|
5 | 3 | 6 | 6 | 6 |
7 | 6 | 6 | 9 | 9 |
9 | 9 | 9 | 9 | 9 |
11 | 9 | 12 | 12 | 12 |
13 | 12 | 12 | 15 | 15 |
15 | 15 | 15 | 15 | 15 |
17 | 15 | 18 | 18 | 18 |
19 | 18 | 18 | 21 | 21 |
-- When the significance is negative, CEILING and ISO.CEILING -- behave differently -- -- CEILING rounds towards the smaller value ISO.CEILING rounds towards -- the largest one. This is important with negative significance DEFINE VAR Vals = GENERATESERIES ( -20, 0, 3 ) VAR Significance = -3 EVALUATE ADDCOLUMNS ( Vals, "FLOOR", FLOOR ( [Value], Significance ), "CEILING", CEILING ( [Value], Significance ), "ISO.CEILING", ISO.CEILING ( [Value], Significance ) )
Value | FLOOR | CEILING | ISO.CEILING |
---|---|---|---|
-20 | -18 | -21 | -18 |
-17 | -15 | -18 | -15 |
-14 | -12 | -15 | -12 |
-11 | -9 | -12 | -9 |
-8 | -6 | -9 | -6 |
-5 | -3 | -6 | -3 |
-2 | 0 | -3 | 0 |
