SYNOPSIS

 use Math::Simple qw(logb log2);
 my $low            =  min($a,$b, $c, $d ...);    # least positive num
 my $hi             =  max($a,$b);                # most positive num
 my $digits_ƒ       =  sub ($) {int log10($_[0]); # log10 default export  
 my $log_in_base    =  logb($base,$num);          # log arbitrary base
 my $log16_ƒ        =  logb(16);                  # create log16 func 
 my $bits_needed_ƒ  =  sub ($) {int log2($_[0])};
 use constant mbits => log2(~1);                  # compile constant

DESCRIPTION

Very simple math routines that I end up re-using in many progs and libified for easy access.

Currently five function, three exported by default. Default exports are min(), max() and log10(). Optional exports are log2 and logb. Note on <logb>: it returns a log in any base, with the base as the first param, and number as the 2nd param, but given 1 parameter (the base), it will return a function ref that only returns that base.

Math::Simple uses Xporter, so including logb or log2 doesn't break the defaults import list see Xporter.
