NAME <\/a> <\/h2>\n

MDK::Common::Math \u2212 miscellaneous math functions<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

use MDK::Common::Math qw(:all);<\/p>\n

EXPORTS <\/a> <\/h2>\n\n\n
<\/td>\n\n

$PI<\/p>\n<\/td>\n

<\/td>\n\n

the well-known constant<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

even( INT<\/small> )
odd( INT<\/small> )<\/p>\n

is the number even or odd?<\/p>\n

sqr( FLOAT<\/small> )<\/p>\n

sqr(3) gives 9<\/p>\n

sign( FLOAT<\/small> )<\/p>\n

returns a value in { \u22121, 0, 1 }<\/p>\n

round( FLOAT<\/small> )<\/p>\n

“round(1.2)” gives 1, “round(1.6)” gives 2<\/p>\n

round_up( FLOAT, INT<\/small> )<\/p>\n

returns the number rounded up to the modulo: “round_up(11,10)” gives 20<\/p>\n

round_down( FLOAT, INT<\/small> )<\/p>\n

returns the number rounded down to the modulo: “round_down(11,10)” gives 10<\/p>\n

divide( INT, INT<\/small> )<\/p>\n

integer division (which is lacking in perl). In array context, also returns the remainder: “($a, $b) = divide(10,3)” gives “$a is 3” and “$b is 1”<\/p>\n

min( LIST<\/small> )
max( LIST<\/small> )<\/p>\n

returns the minimum\/maximum number in the list<\/p>\n

or_( LIST<\/small> )<\/p>\n

is there a true value in the list?<\/p>\n

and_( LIST<\/small> )<\/p>\n

are all values true in the list?<\/p>\n

sum( LIST<\/small> )
product( LIST<\/small> )<\/p>\n

returns the sum\/product of all the element in the list<\/p>\n

factorial( INT<\/small> )<\/p>\n

factorial(4) gives 24 (4*3*2)<\/p>\n

OTHER <\/a> <\/h2>\n

the following functions are provided, but not exported:
factorize( INT<\/small> )<\/p>\n

“factorize(40)” gives “([2,3], [5,1])” as 40\u00c2\u00a0=\u00c2\u00a02^3\u00c2\u00a0+\u00c2\u00a05^1<\/p>\n

decimal2fraction( FLOAT<\/small> )<\/p>\n

“decimal2fraction(1.3333333333)” gives “(4, 3)” ($PRECISION is used to decide which precision to use)<\/p>\n

poly2(a,b,c)<\/p>\n

Solves the a*x2+b*x+c=0 polynomial: “poly2(1,0,\u22121)” gives “(1, \u22121)”<\/p>\n

permutations(n,p)<\/p>\n

A(n,p)<\/p>\n

combinaisons(n,p)<\/p>\n

C(n,p)<\/p>\n
