Deci written

# Text into a deci goes by the value: "1234567.0" is 1234567, seven digits, and a deci32 holds seven, as
# `to.int32[2.0]` is 2. `.written` counts the digits as written instead, trailing zeros included
# (owner, 2026-10-09: "I think there should be a way to say what you want", then "yea, `.written`").
