Displaying p values without leading zero

[Andrzej Niemierko]

Is there a format option (or a trick) to display numbers like 0.03 without the leading zero? That is, as .03? Some journals require p values to be displayed without the leading zero. It's no problem when writing a text, but it is a problem when displaying p values in figures, for example using caption option with p value being a local macro. Any other solution then using graph editor?

Does this help? (Otherwise we sorely and surely need a context of where the P-values are coming from and how they are provided.)

. local have "0.001"

. local want = substr("`have'", 2, .)

. di "`want'"
.001

Thanks Nick, indeed that's what I needed. The p values (from log-rank test) are calculated on the fly in a loop and used in figures as local macros.
