  issue 4 (SUBS_RE is buggy) Status changed by debert   -   Hi Helmut. Sorry for taking this long to get back. Well turns out that the solution was much simpler, instead of rellying on a buggy toPrecision implementation, we can just defer to the the native Number.toFixedPrecision. Fixed in rev 18. I've also included a regression test for this issue. Thanks for the detailed write up. Cheers Arthur Debert

  issue 4 (SUBS_RE is buggy) commented on by helmut.messerer   -   unfortunately Nate Cook's code has a bug too... my final version for truncateNumber() now looks like this: function truncateNumber(raw : Number, decimals :int =2) : String { // Nate Cook's brainchild var intPortion:String = ''; var decPortion:String = ''; var value :String = String(raw); if (value.indexOf('.') == -1) { intPortion = (Math.abs(Number(value))).toString(); decPortion = "0"; } else { intPortion = (Math.abs(Number(value.substring(0,value.indexOf('.'))))).toString(); decPortion = value.substr(value.indexOf('.') + 1); } // create decimal portion if (Number(decPortion) == 0) { decPortion = ''; while (decPortion.length < decimals) decPortion += '0'; } else { if (decPortion.length > decimals) { var dec:Number = Math.round(Math.pow(10, decimals) * Number('0.' + decPortion)); if(((String(dec)).length > decimals) && (dec != 0)) { decPortion = '0'; intPortion = ((Math.abs(Number(intPortion)) + 1) * (Number(intPortion) >= 0 ? 1 : -1)).toString(); } else { decPortion = String(dec); // bugfix here: while(decPortion.length < decimals) decPortion = '0' + decPortion; } } if (decPortion.length < decimals) { decPortion = new String(decPortion); while(decPortion.length < decimals) decPortion += '0'; } } // combine pieces if(decimals == 0) return intPortion; else return intPortion + '.' + decPortion; // old buggy code: // var power : int = Math.pow(10, decimals); // return Math.round(raw * ( power )) / power; }

  issue 4 (SUBS_RE is buggy) commented on by helmut.messerer   -   in order to fix the decimals for this I adapted Nate Cooks AS2 sprintf class a bit and changed truncateNumber() as follows: function truncateNumber(raw : Number, decimals :int =2) : String { var intPortion:String = ''; var decPortion:String = ''; var value :String = String(raw); if (value.indexOf('.') == -1) { intPortion = (Math.abs(Number(value))).toString(); decPortion = "0"; } else { intPortion = (Math.abs(Number(value.substring(0,value.indexOf('.'))))).toString(); decPortion = value.substr(value.indexOf('.') + 1); } // create decimal portion if (Number(decPortion) == 0) { decPortion = ''; while (decPortion.length < decimals) decPortion += '0'; } else { if (decPortion.length > decimals) { var dec:Number = Math.round(Math.pow(10, decimals) * Number('0.' + decPortion)); if(((String(dec)).length > decimals) && (dec != 0)) { decPortion = '0'; intPortion = ((Math.abs(Number(intPortion)) + 1) * (Number(intPortion) >= 0 ? 1 : - 1)).toString(); } else decPortion = String(dec); } if (decPortion.length < decimals) { decPortion = new String(decPortion); while(decPortion.length < decimals) decPortion += '0'; } } // combine pieces if(decimals == 0) return intPortion; else return intPortion + '.' + decPortion; // var power : int = Math.pow(10, decimals); // return Math.round(raw * ( power )) / power; } seems to work for me.

  issue 4 (SUBS_RE is buggy) reported by helmut.messerer   -   What steps will reproduce the problem? 1. printf("%.2f", 0.0) What is the expected output? What do you see instead? 2. returns %.2f 3. instead of 0.00 What version of the product are you using? On what operating system? last Please provide any additional information below. SUBS_RE seems wrong. i changed it to this instead: var SUBS_RE : RegExp = /%(?!^%)(\((?P<var_name>[\w_\d]+)\))?(?P<padding>[0-9]{1,2})?(\.(? P<precision>[0-9]+))?(?P<formater>[sxofaAbBcdHIjmMpSUwWxXyYZ])/ig; note how the precision part is moved AFTER the padding and BEFORE the formater (as it should) this doesn't enforce .00 though (in case of %.2f when supplied integer arguments)

  issue 3 (Formatting a numeric value with a fixed number of decimal pl...) commented on by msielski   -   Having this problem in rev 16. This formats with 2 decimal precision: trace(printf("%f", 1.111); outputs 1.11 but this: trace(printf("%.2f", 1.111); outputs %.2f Fortunately the output of %2 is what I need so I'm using that.

  issue 3 (Formatting a numeric value with a fixed number of decimal pl...) commented on by drukepple   -   Just an "edit" to say that while the characters in my var SUBS_RE line seem to have been preserved, a hard line break was introduced between a "?" and the "P<formatter>", so if you're copying and pasting, be sure to make sure no whitespace exists in the regex after you paste.

  issue 3 (Formatting a numeric value with a fixed number of decimal pl...) commented on by drukepple   -   Hi, I was experiencing the same issue. I got into the regex that parses the raw string and it looks to me like we just need to move the "precision" capture, and place a "?" after it to make it optional. That is: line 48, first line of code of the printf function, might work better like this: var SUBS_RE : RegExp = /%(\((?P<var_name>[\w_\d]+)\))?(?P<padding>0[0-9])?(\.(?P<precision>[0-9]+))?(? P<formater>[sxofaAbBcdHIjmMpSUwWxXyYZ])?/ig; (hopefully that doesn't get destroyed by the HTML page) I did not test this against the various test files, just tested that %.2f and %s both seem to work with that change. Sorry...but I've got a deadline to meet!

  issue 3 (Formatting a numeric value with a fixed number of decimal pl...) reported by lorenzo.wood   -   What steps will reproduce the problem? 1. import the printf 2. execute the code v = printf("%.2f", v), with v an untyped variable originally containing a floating point number (eg, 0.4858329, 5.094833) 3. look at v What is the expected output? What do you see instead? v should contain a string with the numeric value to two DP (eg, "0.486", "5.095" for the example values). In fact, it simply repeats the formatting string (eg, "%.2f" for all values of v). Removing the ".2" qualification, leaving a format string of "%f", produces the expected result. What version of the product are you using? On what operating system? The ZIP file describes itself as "rev6". Running Adobe Flash CS3 and Flash Player 9 on Windows XP SP3. Please provide any additional information below.
