the preferred format is: "@(#) $rcsfile: nss-guidelines.html, v $ $revision: 48936 $ $date: 2009-08-11 07:45:57 -0700 (tue, 11 aug 2009) $ $name$" you can put the string in a comment or in a static char array.
... here is an example from lib/base/baset.h: #ifdef debug static const char baset_cvs_id[] = "@(#) $rcsfile: nss-guidelines.html, v $ $revision: 48936 $ $date: 2009-08-11 07:45:57 -0700 (tue, 11 aug 2009) $ $name$"; #endif /* debug */ the difference, between this and id, is that id has some useless information (every file is "experimental"), and doesn't have name.

Working with data
creating a 64-bit value using a string you can simply pass a string representation of a 64-bit number into the int64 or uint64 constructor, like this: var num1 = ctypes.int64("400000000000"); var num2 = ctypes.uint64("-0x1234567890abcdef"); as you can see, you can use this technique with both decimal and hexadecimal source strings.
...for example: var num = ctypes.int64.join(-0x12345678, 0x90abcdef); performing arithmetic with 64-bit values the int64 and uint64 objects don't provide any methods for performing arithmetic, which means you'll have to do it yourself by pulling out the high and low 32-bit portions and doing math on them, then joining them back together if necessary to get the complete result.

for example, we can expand the entry for bubblesort(): so we can see the call graph is like this: sortall() -> sort() -> bubblesort() note also that self cost for sort() here is 1.45%, and note that this is the same as for the separate entry for sort() later in the list.
... with this kind of digging, we can figure out the whole call graph, with associated sample count: sortall() // 8 -> sort() // 37 -> bubblesort() // 1345 -> swap() // 252 -> selectionsort() // 190 -> swap() // 1 -> quicksort() // 103 -> partition() // 12 platform data you'll also see some rows labeled gecko, input & events, and so on.

rectangular shape example <html> <body onload="draw();"> <canvas id="canvas" width="150" height="150"></canvas> </body> </html> function draw() { var canvas = document.getelementbyid('canvas'); if (canvas.getcontext) { var ctx = canvas.getcontext('2d'); ctx.fillrect(25, 25, 100, 100); ctx.clearrect(45, 45, 60, 60); ctx.strokerect(50, 50, 50, 50); } } this example's output is shown below.
...ht="150"></canvas> </body> </html> function draw() { var canvas = document.getelementbyid('canvas'); if (canvas.getcontext) { var ctx = canvas.getcontext('2d'); // filled triangle ctx.beginpath(); ctx.moveto(25, 25); ctx.lineto(105, 25); ctx.lineto(25, 105); ctx.fill(); // stroked triangle ctx.beginpath(); ctx.moveto(125, 125); ctx.lineto(125, 45); ctx.lineto(45, 125); ctx.closepath(); ctx.stroke(); } } this starts by calling beginpath() to start a new shape path.

Drawing graphics - Learn web development
let's try adding another arc: ctx.fillstyle = 'yellow'; ctx.beginpath(); ctx.arc(200, 106, 50, degtorad(-45), degtorad(45), true); ctx.lineto(200, 106); ctx.fill(); the pattern here is very similar, but with two differences: we have set the last parameter of arc() to true, meaning that the arc is drawn counterclockwise, which means that even though the arc is specified as starting at -45 degrees and ending at 45 degrees, we draw the arc around the 270 degrees not inside this portion.
Handling text — strings in JavaScript - Learn web development
you can include complex expressions inside template literals, for example: let examscore = 45; let examhighestscore = 70; examreport = `you scored ${ examscore }/${ examhighestscore } (${ math.round((examscore/examhighestscore*100)) }%).

JavaScript object basics - Learn web development
setting object members so far we've only looked at retrieving (or getting) object members — you can also set (update) the value of object members by simply declaring the member you want to set (using dot or bracket notation), like this: person.age = 45; person['name']['last'] = 'cratchit'; try entering the above lines, and then getting the members again to see how they've changed, like so: person.age person['name']['last'] setting members doesn't just stop at updating the values of existing properties and methods; you can also create completely new members.
