Convert float to integer

[Sarah Fabito]

Hi, I have a variable name "age" However, there are values like 6.01. How will I convert all 6.01 to just 6? Thank you.

So, it depends on how you want to handle values like 6.6. Do you want that to go to 6, or to 7? There are different ways, that work differently:

input x
6
6.2
6.5
6.7
7
end

gen y1 = floor(x)
gen y2 = ceil(x)
gen y3 = round(x)
list, noobs clean

Nice. Thank you!

Many would agree that from the body of your post one can guess what you want, but the body _with_ the title, strictly speaking, is ambiguous.

Pedantically, notice the following:

1) float and int are storage types in Stata. Clyde's code will shave off decimals but variables will still have storage type float (the default) [nothing wrong with that; see -help float- anyway]:

. clear

. set more off

.
. input x

             x
  1. 6
  2. 6.2
  3. 6.5
  4. 6.7
  5. 7
  6. end

.
. gen y1 = floor(x)

. gen y2 = ceil(x)

. gen y3 = round(x)

2) From -help data types-: "Numbers are stored as byte, int, long, float, or double, with the default being float. byte, int, and long are said to be of integer type in that they can hold only integers."

3) You can create integer types, specifying so with the -gen- command:

. gen int y1 = floor(x)

. gen int y2 = ceil(x)

. gen int y3 = round(x)

y3              int    %8.0g                  
----------------------------------------------------------------------------

4) Be careful when doing just that, as different storage types can hold more or less numbers. Again see, -help data types-.

The whole purpose of this, is really nothing more than to point out some linguistic features of your post in relation to Stata terminology. Maybe the clarification will prove helpful in the future.
