Pas reproductible pour moi non plus:

[pauamma at gadfly] ~% perl -e 'use Math::Trig;use bignum; printf 
"%g\n",2.0*pi;'
6.28319
[pauamma at gadfly] ~% perl -MMath::Trig -Mbignum -e 'printf "%g\n",2.0*pi'
6.28319
[pauamma at gadfly] ~% perl -v

This is perl 5, version 32, subversion 1 (v5.32.1) built for 
amd64-freebsd-thread-multi
[...]
[pauamma at gadfly] ~% uname -a
FreeBSD gadfly 12.3-RELEASE-p6 FreeBSD 12.3-RELEASE-p6 GENERIC  amd64
