round

Command: round


Synopsis
double round -> double
integer round -> double

Alternatives: Function round_d (undocumented)
-> behaviour and synopsis are the same.

File
lib/sli/ps-lib.sli
Author
introduced non-trie-variant round_d Ruediger Kupper.

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.


Examples

1.4 round --> 1.0
1.5 round --> 2.0
2 round --> 2.0
