Round
Sometimes the round() function does not perform its job.
For instance, in this case round does not change anything to the value of the local toto.
. local toto = 9.950000000000001
. di "`toto'"
9.950000000000001
. local toto2 = round(`toto',.01)
. di "`toto2'"
9.950000000000001
The temporary solution to this problem is to treat toto as a string and to use regexm to round it :
. local toto = 9.950000000000001
. di "`toto'"
9.950000000000001
. if regexm("`toto'","([0-9].[0-9][0-9])"){
. local toto = regexs(1)
. di "`toto'"
9.95
. }
