The term "decimal point" does not technically apply when using bases other than 10; the more generic term is "radix point". Update the description of the a/A conversion specifier (i.e., for hexadecimal floating point output) in printf(3) to use this terminology. I do note that POSIX.1-2024 [1] does use the term "decimal-point character" here, but I still maintain that using "radix point" is a better term for that object in the %a description. (Confusingly, POSIX does refer to "radix character" in the descriptions of %f and %e, where reference to "decimal" instead of "radix" would actually make sense.)
