It&#x27;s a shame the C&#x2F;C++ standards committee(s) didn&#x27;t just copy Verilog&#x27;s base-n notation when they added the &quot;0b&quot; prefix.  It&#x27;s nice to be able to write large constants with optional underscores every four or eight digits, e.g. 32&#x27;hffff_0867_5309_beef, or 12&#x27;b1101_1110_1010.
