| Name: | round - Round double to the nearest integer
|
| Synopsis: | double round -> double
integer round -> double
|
| Description: | Alternatives: Function round_d (undocumented)
-> behaviour and synopsis are the same.
|
| Examples: |
1.4 round --> 1.0
1.5 round --> 2.0
2 round --> 2.0
|
| Remarks: |
round_d is currently defined in SLI,
could be implemented in C++ for efficiency.
On 130610 it was decided that round applied to an integer
should be the identity function.
Update: In a later discussion, it was decided to make round
return a double in this case as well.
