COBOL is easy. JCL is the hard part.
* Is a type in the standard library "baked in"? I lean towards no, but I'll give the language A for effort anyway.
1) Python - added to the standard library in 2003.
2) C - no.
3) Java - BigDecimal in the standard library.
4) C++ - no.
5) C# - built in.
6) VB - Currency type kinda does what you'd want, but doesn't scale down very far.
7) Javascript - no. (Use https://github.com/MikeMcl/bignumber.js)
8) SQL - Yes. But check your dialect.
9) PHP - No.
10) Go - No. (Use https://pkg.go.dev/github.com/shopspring/decimal)That's a fact. A couple of years ago, I had to brush off my JCL skills for a job. It reminded me of why I was so happy when I didn't have to use JCL anymore.
