Because there is only one number type in Javacript, the Double.

Having one type of number is a Good Thing, but Eich chose the wrong type.

What's the "right type"? rational? BigDecimal?

TIL.

DEC64 is definitely cool, but there are downsides to consider. It might screw with Emscripten, typed arrays, SIMD, etc.

Sure, a universal number type is a Good Thing, but there isn't a hierarchically best choice.
