I use a layout with an AZERTY-style shifted digit row for coding (and for everything else). A quick check of one C++ codebase I've been working with shows ~20× as many instances of digit-row symbols as digits (18× for QWERTY digit-row symbols, 27× for those in my layout), though C++ is unusually symbol-heavy. A couple of ECMAScript repositories show 3× or 10×. On some Common Lisp, digit-row symbols are 5× as common as digits for my layout and 22× for QWERTY (almost entirely because QWERTY parentheses are terrible). I don't expect to see a lot of code where numeric literals are more common than type modifiers and operators and such… most of the times numbers are being manipulated in code, they're not being typed in directly as digits but going through comparisons and arithmetic and such, and that's symbols.
