A power of 2 is not divisible by 5 and hence not by 10 so it cannot end
in a zero. So any answer with a trailing zero is wrong.

For what it's worth, Matlab produces 72057594037927936. 

In general, 64-bit math is limited in accuracy to between 16 and 17 decimal 
digits, depending how well that number "fits" into a floating point 
representation.

16 to the power 14 is indeed 72057594037927936. Calculator is absolutely 
correct. It is presumably doing high-precision integer arithmetic. 

ActionScript is using floating point arithmetic, since you can ask for things 
like Math.pow(16.1, 14.2). It doesn't special case on integers, and even if it 
did it doesn't do high-precision integer arithmetic. It gets the wrong answer 
because floating-point numbers don't have a sufficient number of significant 
digits to produce a 17-digit result exactly. It simply computes powers by 
taking the log() of the first argument, multiplying it by the second argument, 
and then taking the exp() of the result, because a^b = e^(ln(a^b)) = e^(b 
ln(a)). These are all floating-point operations.

 NO NO NO.
 
16 to the power 14 is indeed 72057594037927936. Calculator is absolutely 
correct. It is presumably doing high-precision integer arithmetic.
 
ActionScript is using floating point arithmetic, since you can ask for things 
like Math.pow(16.1, 14.2). It doesn't special case on integers, and even if it 
did it doesn't do high-precision integer arithmetic. It gets the wrong answer 
because floating-point numbers don't have a sufficient number of significant 
digits to produce a 17-digit result exactly. It simply computes powers by 
taking the log() of the first argument, multiplying it by the second argument, 
and then taking the exp() of the result, because a^b = e^(ln(a^b)) = e^(b 
ln(a)). These are all floating-point operations.

Re: Math.pow in ActionScript

2014-11-11 Thread Harbs
I’m not sure why you think it’s not using floats.

Take a look here:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Math.html

Specifically:
Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and 
sqrt may result in slightly different values depending on the algorithms used 
by the CPU or operating system. Flash runtimes call on the CPU (or operating 
system if the CPU doesn't support floating point calculations) when performing 
the calculations for the listed functions, and results have shown slight 
variations depending upon the CPU or operating system in use.

Hi,

I am using Math.pow(x,y) method in action script. But I am very surprised with

For example, Math.pow(16,14).

In Action Script, it gives:72057594037927940
In Calculator, it gives:  72057594037927936

What may be the reason for this difference , Any idea !

I am using Math.pow(x,y) method in action script. But I am very surprised with
