Hi All,

This may be a stupid question. Here are the command and Stata output:

.set obs 50
.gen a=100.1
.count if a==100.1
.tab a
.sum a
variable  obs  mean  s.d.  min    max
a            50    100.1  0    100.1  100.1
.gen b=a-100
.tab b

So, Stata shows that a is equal to 100.1, but actually, it is equal to

Can anyone explain to me what this is? Do I have to set precision when
I do math in Stata? How to set precision?
