Hi Florence,
It seems to work ok if you declare the non-decimal version as a
"long" (integer).
KD
. version
version 8.2
. clear
. input double x
x
1. 150.089873
2. end
. format x %10.6f
. gen long y=x*1e6
. describe
Contains data

y long %12.0g

. list, clean

1. 150.089873 150089873

Hello, I have a question, I have variables that are coded in as 2-3
digits and 6 decimal places after that, e.g. 150.089873 and I want
to convert this to get rid of the decimal places so it looks like
150089873 but when I just multiply by 1000000 then it keeps storing
it as a "float" display i.e. 1.5E8 and more than that, the last
decimal places are actually INCORRECT in the new version...it will
say 1.50089875 instead...which is INCORRECT. I am using Stata 8 and
that is where this problem occurs. I was wondering what the easiest
way is to change datatypes that something is input in so that it
will not be a problem.
Thanks,
florence
