in reply to sprintf number to string

Hello jobsworth,

Perhaps this will shed some light:

(1) Without warnings:

23:59 >perl -E "$c = 1; say(length $c);" 1 23:59 >perl -E "say(length $c);" 23:59 >perl -E "$c = sprintf('%d', $c); say(length $c);" 1 23:59 >

(2) With warnings:

23:59 >perl -wE "$c = 1; say(length $c);" 1 0:01 >perl -wE "say(length $c);" Name "main::c" used only once: possible typo at -e line 1. Use of uninitialized value in say at -e line 1. 0:01 >perl -wE "$c = sprintf('%d', $c); say(length $c);" Use of uninitialized value $c in sprintf at -e line 1. 1 0:01 >

Hope that helps,
