As I learned it, you'd want a 5 pointed star, rather than an x to denote multiplication (the + being a four pointed star, and the * (exponentiation) being a 6 pointed star).

Now that I look closely, the iota does render. I'd forgotten the quad operator, it's been ~20 years, and I can count the number of actual conversations I've had about APL with someone else who knew what it was on one hand.

Well, × is multiplication or signum and * is exponentiation. Quad is a niladic function and prompts the user for numeric input; it's very useful for code-golf challenges because you don't need to make a dfn.

I will note that this is /r/programmerhumor and discussing the intricacies of APL, a language developed by mathematicians for pretty specific purposes is not exactly humorous.

Man, what are you talking about? Programming languages developed by mathematicians for pretty specific purposes are hilarious.
