AW: st: AW: float to numeric??

You are thinking in terms of percentages, as in some spreadsheets, Stata is
not. To Stata, "0.1" is _not_ 10%. If you want Stata to turn this into
integers, create a variable 
"chipeligrate_as_percent", multiplying your "chipeligrate" by 100. It is
your responsibility that in future, this convention will be remembered when
you or others use the data.

Hi Martin,

I am really confused.  I have been a stata user for some time but clearly
I am not as strong as many of you.

Please do tell, why??  this chip elig rate simply is an eligibility rate
at the state level-- can be between 10% and 400% of the FPL hence-- .1 to
4 varying values.  I do not neet a complicated definition. or 9 decimals
etc.

Please help me what I can do to make this variable more user friendly. 
All I need is 2 decimals.  As I think some states have eligibility of 185
% or 17% etc.

I also do not understand why float function as some recommended below does
not work.  Without the float. the calculation:

replace eligstatus = 1 if chipeligrate ==1.92 & (povcat == 1 | povcat == 2)
replace eligstatus = 2 if chipeligrate ==1.92 & (povcat == 3)
replace eligstatus = 3 if chipeligrate ==1.92 & (povcat == 4)

will work for instance for values where povcat == 3 or povcat == 4 but
will NOT work for obs. where povcat == 1 | 2?? returning missing values
for those obs. for the eligstatus variable.  I have no explanation for
that.  If the value is stored as float, shouldn't the calculation NOT work
for all values??

I am still confused.  I aprpeciate all your help with this.

Thank you.
