Background
R/exams is a great tool for generating exams for students.
Problem
When a numeric exercise has a large solution, an error is thrown:
Error in string2num(exsolution) :
all numeric items must be finite and non-missing
Is this a bug or am I missing something out?
Minimal example
Here's a minimal exercise ("test-debug.Rmd") that provoked the error:
Question
========
Some text
Solution
========
Some solution
```{r}
sol <- 1e4
```
Meta-information
================
exname: test-debug
extype: num
exsolution: `r sol`
I used exams2html
to render the exercise:
exams2html(file = "test-debug.Rmd",
edir = path_to_exercise,
dir = path_output)
System info
exams 2.4-0
CodePudding user response:
exsolution: `r fmt(sol, digits = 3)`
