Subject: st: How to deal with the accruacy of storage type?
I encountered a problem on the accuracy of storage type.
For example, I typed the following in the stata,
clear
input x y
.46520616 .4652062
.02347426 .0234743
.01774185 .0177418
.04014428 .0401443
.24818808 .2481881
.41385191 .4138519
.27035237 .2703524
.03764375 .0376438
.22899382 .2289938
.08620364 .0862036
end
l
count if x==y
The result of "count if x==y" is 0. However, in my actual matter, this
situation should be treated as equal between x and y if the # digits (such
as four or five) after decimal are the same.
What is the right command to express the above meaning?
Thank you a lot for any help.
Best regards,
Rose.
