FOUR KINDS OF NUMBERS
-Numbers can be decimal, hexadecimal, octal or binary. A hexadecimal number
-starts with "0x" or "0X". For example "0x1f" is decimal 31. An octal number
-starts with a zero. "017" is decimal 15. A binary number starts with "0b" or

+Numbers can be decimal, hexadecimal, octal or binary.
+
+A hexadecimal number starts with "0x" or "0X". For example "0x1f" is decimal
+31.
+
+An octal number starts with "0o", "0O" or a zero and another digit. "0o17" is
+decimal 15. Using just a zero prefix is not supported in Vim9 script.
+
+A binary number starts with "0b" or "0B". For example "0b101" is decimal 5.
+
+A decimal number is just digits. Careful: don't put a zero before a decimal
+number, it will be interpreted as an octal number in legacy script!
+
+The ":echo" command always prints decimal numbers. Example: >
:echo 0x7f 0o36
