NAME
Math::Factor::XS - Factorise numbers and calculate matching
multiplications
SYNOPSIS
use Math::Factor::XS ':all';
$number = 30107;
@factors = factors($number);
@matches = matches($number, @factors);
print "$factors[1]\n";
print "$number == $matches[0][0] * $matches[0][1]\n";
DESCRIPTION
Math::Factor::XS factorises numbers by applying modulo operator
divisons.
FUNCTIONS
factors
Factorises numbers.
@factors = factors($number);
$number will be entirely factorised and its factors will be saved within
the array @factors.
matches
Evaluates matching multiplications.
@matches = matches($number, @factors);
The factors within @factors will be multplicated against each other and
results that equal the number itself, will be saved to the
two-multidimensional array @matches. The matches are accessible through
the indexes, for example, the first two numbers that matched the number,
may be accessed by $matches[0][0] and $matches[0][1], the second ones by
$matches[1][0] and $matches[1][1], and so on.
If $Math::Factor::XS::Skip_multiple is set to a true value, matching
multiplications that contain multiplicated (small) factors will be
dropped.
Example:
# accepted
30107 == 11 * 2737
# dropped
30107 == 77 * 391
