2.05 Number Rounding
Four number rounding methods have been identified for inclusion in this data book.
Type-1: The higher integral multiple is selected as rounded number
nnn.0 through nnn.4 round to nnn | ex. 123.4 --> 123 |
nnn.5 through nnn.9 round to nn(n+1) | ex. 123.5 --> 124 |
nnn.nn0 through nnn.nn4 round to nnn.nn | ex. 123.454 --> 123.45 |
nnn.nn5 through nnn.nn9 round to nnn.n(n+1) | ex. 123.455 --> 123.46 |
Type-2: The even integral multiple is selected as the rounded number
and 123.55 --> 123.6
Type-3:
nnn.nn1 and nnn.nn2 round to nnn.nn0 | ex. 123,452 --> 123.450 |
nnn.nn3 through nnn.nn7 round to nnn.nn5 | ex. 123.454 --> 123.455 |
nnn.nn8 and nnn.nn9 round to nnn.n(n+1)0 | ex. 123.458 --> 123.460 |
nn.(n-1)76 through nn.n25 round to nn.n0 | ex. 123.325 --> 123.30 |
nn.n26 through nn.n75 round to nn.n5 | ex. 123.326 --> 123.35 and 123.376 --> 123.40 |
China | CNA | 1 |
Hong Kong | HKG | 1 |
India | IND | 1 |
Indonesia | INA | 1 |
Japan | JPN | 1 |
Korea | KOR | 1 |
Malaysia | MAS | 1 |
Philippines | PHI | 1 |
Singapore | SIN | 1 |
Thailand | THI | 1 |
rem-1: | Above country data are not considered any CEILING and/or FLOOR types of rounding. |
Those are rather application (such as Accounting/Taxing) dependent rounding. | |
CEILING: 123.011 --> 123.02 | |
FLOOR: 123.019 --> 123.01 | |
rem-2: | Related standards: ISO 30-0, IS 2, JIS Z 8401, KS A 0021 |
