However, if Wren is embedded in a suitable C program, then we can ask the latter to call it for us and pass back the result.

class Interval {

construct new(lower, upper) {

 

Note that Wren's built-in print statement never displays numbers with more than 14 digit accuracy. However, if the interval bounds had been displayed directly from C with 17 digit accuracy (the maximum for the 'double' type), there would have been a marginal difference between them, namely: [1.2299999999999998, 1.2300000000000002].

WrenVM* vm = wrenNewVM(&config);

const char* module = "main";

WrenInterpretResult result = wrenInterpret(vm, module, script);
