This code prints the values of left-margin-default (always 15mm) and 
left-margin-default-scaled (varies with the size of the paper). The 
scaled margins are always an exact number of mm so it looks like 
rounding to the nearest mm is happening somewhere.

\version "2.26.0"

% #(set-default-paper-size "letter")
% #(set-default-paper-size "a3")
#(set-default-paper-size '(cons (* 8.6 in) (* 11 in)))

lmargin = #(ly:output-def-lookup $defaultpaper 'left-margin-default)
lmargin-scaled = #(ly:output-def-lookup $defaultpaper 
'left-margin-default-scaled)
#(ly:message "~s ~s\n" lmargin lmargin-scaled)
