> formatting is more common than parsing.

Is it, though? It's genuinely hard for me to tell.

There's both serialization and deserialization of data sets with, e.g., JSON including floating point numbers, implying formatting and parsing, respectively.

Source code (including unit tests etc.) with hard-coded floating point values is compiled, linted, automatically formatted again and again, implying lots of parsing.

Code I usually work with ingests a lot of floating point numbers, but whatever is calculated is seldom displayed as formatted strings and more often gets plotted on graphs.
