Re: [Jprogramming] Displaying stock market data

I tried searching the wiki and noticed that there is a "printf" add-on for C-like formatting. Also, I recall that there is something that uses text format specifiers, like '<9.3d>' or such. I know I've used it but cannot find the code or a reference on the J site. On Thu, Sep 12, 2019 at 12:38 A

Re: [Jprogramming] Displaying stock market data

I'm puzzled.  When you look at https://code.jsoftware.com/wiki/Vocabulary/quoteco#dyadic , the second example uses a complex x to control formatting.  If you read on in the detail, you see complex x used repeatedly. Do this: go back to that page and read carefully, especially after "More Info

[Jprogramming] Displaying stock market data

Although I can find general print precision in the J documentation, I can't seem to find how to display 2 decimal digits, 3 decimal digits, or 4 decimal digits, for example. In other words, I don't really care how many digits precede the decimal point, but I need to have a fixed number of digits f
