Using ToString() to format scientific notation...

[funk101]

I'm getting the return from Slope() which is a double and expressed as scientific notation.
For example:

double myRes = Slope(blah, blah);

printing myRes displays -> 2.249999999999984E-06

I would like to display/format myRes like this:

2.24 or maybe 2.249. etc.

Problem is when I do this:

myRes.ToString("0.00");

I get -> 0.00

This approach seems to work in other situations, why not here?

Try this:

myRes.ToString("N4")

If it's an indicator output and you want more decimal places on your chart, you need to override FormatPriceMarker:

public override string FormatPriceMarker(double price)
{
return price.ToString("N4"); //Formats price values to 4 decimal places
}

Thank you , that worked, however...

I'm getting 0.0001 as a result from 0.000132249999228991, which is to be expected. In this instance, the number is useless to me. How can I turn that into say 1% or where I can use it as -1%, 1%, 1.5% etc.

Try something like

myRes.ToString("#0.0000 %")

Ok, this is what I got going on...

-- The '\u2030' -> read on:

string fmt = "#0.## "+'\u2030';

myRes * 1000;

myRes.ToString(fmt);

This gives me:

6.5% from 6.49999999...E-06

It's a number that I can use, and means something to me however 'un-mathematically' perfect it may be.
