The -string- command can be combined with a format to render a number as a string with a specified number of decimal places. For instance:
. display string(_pi, "%9.2f")
3.14
. display string(_pi / 100, "%9.2f")
0.03
. display string(_pi / 100, "%9.4f")
0.0314
. display string(_pi * 100, "%9.4f")
314.1593
Am I correct in believing that no comparable method exists for generating a string that shows a specified number of significant digits?
For example, suppose the function was called -sigdig-. Then we would get the following results:
display sigdig( _pi, 3 )
3.14
display sigdig( _pi / 100, 3 )
.0314
display sigdig( _pi * 100, 3 )
314
A google search brings up -esttab-, which evidently creates nice tables of output from regression models. I had in mind however a more general tool.
Thanks for any pointers
