I need high level of precision in my Perl script, so I'm using BigFloat. Everything works well within subroutines, but when I try to pass a BigFloat number from one sub to another it reverts to a regular float. Specifically, I don't think I have a problem putting big numbers into a subroutine, just making getting the output to be a big number. The numbers could be reverting to floats when I put them in the return array, or during the return process. Does anyone know how to: 1) Put BigFloat numbers into an array and 2) Pass BigFloat numbers between subroutines Thanks! Here's a snippet of the code: 
#!/usr/bin/perl
use strict;
use Math::BigFloat;
    Math::BigFloat->accuracy(20);
    
sub simulate_lifespan{
    my $r = Math::BigFloat->new($_[0]);
    my $org_muv = Math::BigFloat->new($_[1]);
    my $org_muy = Math::BigFloat->new($_[2]);
    my $scaler = Math::BigFloat->new($_[3]);
    my $ext_death = Math::BigFloat->new($_[4]);

    my $lifetime_fitness = Math::BigFloat->new(0);
    my $log_lifetime_fitness = $lifetime_fitness->copy();
    $log_lifetime_fitness ->blog();
    my @return_array = ($time, $log_lifetime_fitness, $mean_v, $mean_y
+);
    return \@return_array;
}
