How to scale a double like 1.9416746607144E+36 down so I can use in a winForms chart?


There are many ways of mapping the range [0:10e36] onto the range [0:1] (or whichever concordant system you want.)

The first question you should be asking is: what do values that big actually represent, and if i have 1e24, 1e34 and 1e36 as 'Legitimate' values what would i like to see on the chart.

The simplest answer is in the comment by dbugger above with a simple division to rescale the range, but depending on your use case (very few things end up with a legitimate number that large, check for underflow or almost-div-0 errors) then a rescaling function like log(x) , or x^(1/4)/10e6 re-scaling functions may be more appropriate.

There are only 7.1e9 people on earth, earth weighs 5.98*10e24 kg, the universe is expected to be in existence around 3e20 milliseconds (10 billion years), and there are also approx 10e20 stars in the universe.

The point is 10e36 does not represent any type of phsyical thing, so perhaps working out what you are trying to plot will aid you in describing how to convert those numbers into a sensible plotting range.

Density scale of Y axis mysteriously changed when X scale is transformed to log10
The density should integrate to 1, which still allows the point estimate of the density as some point to exceed 1. However, the reason that the general shape of the density is changing is that scale_x_log10() and coord_trans(x="log10") do different things. In particular, the scale transformation (scale_x_log10()) happens before any statistics (such as density) are computed. So the density that is

jQuery Highcharts double donut chart (donut within donut)
No, it's perfectly possible. It's just bloody difficult. But hey, why not? The problem with High Charts is that you cannot rotate nor position your charts with a specific angle. So to allow you to create the effect you mentioned, we must create a seperate chart for every new data item. Of course, you don't want to hardcode all this so we need generate the code with a for loop, taking into accou

compare Java Double.Max_VALUE with large double numbers returns true
I think the problem is in this line | v new Double(Double.MAX_VALUE).equals(new Double(Double.MAX_VALUE - 99999999999999999999999D)) DOUBLE MAX_VALUE = Double.MAX_VALUE - 99999999999999999999999D AND you're comparing it with new Double(Double.MAX_VALUE - 99999999999999999999999D
