c# - Correct way to store very large integers with maximum performance? -

-

so working on game in store large numbers, in trillions , quadrillions (a progression type game, la clicker heroes, doing fun).

anyway, c# appears have 32-bit limit on integers, however, can floats very large (eg. 999999999999999.0f)

however, fastest way store large numbers in c#?

i not need accuracy, floating point-type solutions fine. need speed , ability store large integers.

is bigint library way go? how recommend going this?

anyway, c# appears have 32-bit limit on integers, however, can floats very large (eg. 999999999999999.0f)

this categorically false. c# has long , ulong types correspond .net's int64 , uint64 types, both 64-bit integers represent number-ranges:

int64 : -9,223,372,036,854,775,808  9,223,372,036,854,775,807 uint64:                          0 18,446,744,073,709,551,615.

that's:

eighteen quintillion, 4 hundred , forty 6 quadrillion, 7 hundred , forty 4 trillion, seventy-three billion, 7 hundred , 9 million, 5 hundred , fifty-one thousand, , 6 hundred , fifteen.

and if need store bigger numbers can implement own uint128 joining 2 uint64 values , using schoolbook techniques combine 2 common arithmetic operations.

javascript - Chart.js (Radar Chart) different scaleLineColor for each scaleLine -

i try , create radar chart using chart.js has various colours each scaleline, or coloured between scalelines. wondering if possible? from: to: i have working graph, though there doesn't seem method change individual scale lines. kind regards leigh you can extend radar chart type this, so chart.types.radar.extend({ name: "radaralt", initialize: function (data) { chart.types.radar.prototype.initialize.apply(this, arguments); var originalscaledraw = this.scale.draw; var ctx = this.chart.ctx; this.scale.draw = function () { var linewidth = this.linewidth; // bypasses line drawing in originalscaledraw this.linewidth = linewidth; originalscaledraw.apply(this, arguments); ctx.linewidth = this.linewidth; var scale = this; // draw chart.helpers.each(scale.ylabels, function (label, index) { // color of ...

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
