RE: [flexcoders] Simple arithmetic - resolved

2005-04-19 Thread Gordon Smith 

Math operations with normal numbers, such as 0/0 and Math.sqrt(-1), can also
produce NaN. 

According to the ECMA-262 spec, NaN is a Number, despite its name meaning
"Not a Number":

"4.3.20 Number Type
The type Number is a set of values representing numbers. In ECMAScript, the
set of values represents the double-precision 64-bit format IEEE 754 values
including the special "Not-a-Number" (NaN) values, positive infinity, and
negative infinity."

The concept of NaN dates back at least to the IEEE 754 specification for
binary floating-point arithmetic.

NaN is kind of its own type and is usually the result of an equation
with a string or some other non-numeric type.

Okay, I'll avoid getting into any language discussion by saying that I
really meant that NaN can be safely assigned to a Number reference
without a cast.

  var x:Number = NaN;

That may or may not mean that NaN is a Number.  Pick up a Colin Moock
book if you care to find out (I don't).  It can be said that NaN is to
Number as null is to Object (but I won't say it, because I already
did).

Solved - turns out I was applying a currency format to the variable before 
handing it to the function so it really was NaN.

Question - shouldn't this have thrown an error, since I was casting the 
non-number variable as a number in the parameter statement, as varX:Number?

RE: [flexcoders] Simple arithmetic

2005-04-17 Thread Tom Fitzpatrick 

OK - here's more info.

I'm passing the returned array as the dataprovider for a list (passed as 
"dataObject"):



The labelFunction is:

 function myLabelFunction(item):String
 {
 return item.label + ": " + item.data;
 }

Does that help?

I thought the string conversion in the function would do the trick, because 
the labelFunction is looking for strings, but that still gives me a NaN.

2005-04-17 Thread Abdul Qabiz 

Hi,

Everything in function seems to be right, I feel something is wrong
somewhere else.

Can you post the code, how you are calling this function.

To isolate the problem, just call this function and show results in alert.

e.g.

alert(getPercentages(80,20,1)[0].data)

I'm trying to pass three numbers to a function and have it return an array 
containing two numbers that will be used as the dataprovider for a list. 
The list uses a labelFunction to display items in the form:

"label": "data"
"label": "data"

for example:

Salary: $80,000
Bonus: $20,000

Here's the latest thing I tried (doesn't work, but shows what I'm shooting 
for):

function getPercentages(varX:Number,varY:Number,varZ:Number)
{
varX= (varX/100)*varZ;
varY= (varY/100)*varZ;
var newSalary = varX.toString();
var newBonus = varY.toString();
var newFigures = [
{label:"Salary",data:newSalary},
{label:"Bonus",data:newBonus}
];
return newFigures;
}

Feeding the numbers

varX = 80
varY = 20
varZ = 100,000

should yield this list:

Salary: $80,000
Bonus: $20,000

Instead, I get:

Salary: NaN
Bonus: NaN

Assuming I've provided enough information, can anyone see what's wrong?
