bits - Large number arithmetic -



bits - Large number arithmetic -

i have read somewhere handle big number arithmetic (really large) should store number in big base of operations @ max squareroot(maxnumber). because representing number in larger base of operations needs little number of digits e.g. 120 in decimal = 1111000 in binary system. if @ store big numbers in big bases, reduces number of bits @ lowest level? don't think because number in hexadecimal number scheme certainly takes little number of digits on paper not on hardware.

i think missing here. help me understand how can store big base of operations number @ bit level in less number of bits?

depends on encoding want utilize .. can binary coded decimals in can code each individual binary digit 4 binary bits ,, or can utilize extended binary representations numbers e.g 128 bit numbers etc.. should able find libraries allow both of above solutions online. p.s bcd take smaller space little numbers huge amount of bits big numbers.. maybe can find variation of bcd not wastefull

c# - Can ProtoBuf-Net deserialize to a flat class? - protobuf-net uses nested protobuf constructs back upwards inheritance. however, can made force properties flat target class has same properties inherited "serialized" version? see test illustration below. needless result of flat namespace null both properties. possible solution: re-create info flat.b first on property property basis. note: not prefered option. using system; namespace hierarchy { using protobuf; [protocontract] public class { [protomember(1)] public string prop1 { get; set; } } [protocontract] public class b : { public b() { } [protomember(1)] public string prop2 { get; set; } public override string tostring() { homecoming "prop1=" + prop1 + ", prop2=" + prop2; } } } namespace flat { using protobuf; [protocontract] p...

javascript - Change element in each JQuery tab to dynamically generated colors - i'm using jquery ui tabs widget , have button add together additional tabs. i'm tying each tab markers on map coordinating randomly generated color using function gen_color() { homecoming '#'+(math.random()*0xffffff<<0).tostring(16); } so each tab has color corresponds number of markers of same color on map. i'm trying add together 15x15 block of color within tab's tab left of it's label. right i'm using tabtemplate alternative , trying alter when new tab added: $tabs = $("#tabs").tabs({ tabtemplate: "<li><span class='ui-icon-color' style='background-color:#000000;'></span><a href='#{href}'>#{label}</a> <span class='ui-icon ui-icon-close'>remove tab</span></li>", selected: 0, add: funct...
