No, 42/13 is 42 over 13, which is 3 + 3/13. Let's not confuse fractions and bases, please.
:13(42) means 54. That much is straightforward. :13(6*9) is less obvious, but seems to mean (1) multiply 6*9, (2) convert the resulting number to a (decimal) string; (3) interpret that string in base 13. Hence :13(54) or decimal 69. Either way, AIUI, the radix is only used to control the interpretation of the literal. The result is just a number, which doesn't "know" that it was entered in base 13. It's just a value, without any inherent notion of a particular radix. Or at least I thought that was the case, but in current Rakudo I notice that :13(54) is a Num while 69 is an Int. -- Mark J.
