doubleToString 0 digit...

[ustk]

Engine.doubleToString(value, 0) doesn't throw a 0 digit string, but 2 digits oscillating with 0 digit...

I know I can use round but it's not practical in my situation. I have a function that needs a different number of digit depending on the value & unit to display. Some need 1, other 0, and other 2 digits Engine.doubleToString(value, object.digit)

Yes, passing 0 as second argument means "give me all digits that are available" (actually I am just forwarding this to a JUCE helper method).

But you can easily write a version that's more suitable for you like this:

namespace GregsEngine
{
    inline function doubleToString(value, numDigits)
    {
        if(numDigits == 0)
            return "" + parseInt(value);
        else
            return Engine.doubleToString(value, numDigits);
    }
}

// client code

Console.print(GregsEngine.doubleToString(2412.0125, 0));
Console.print(GregsEngine.doubleToString(2412.0125, 2));
