The test file `test/clojure/test_clojure/parse.clj` includes this block in `test-parse-double` (lines 57-60):

This has several problems:

• The function being called is `parse-long`, not `parse-double`

• Parsing a number larger than the maximum double will return `Double/POSITIVE_INFINITY`, not `nil`

• Parsing a number smaller than the minimum double will be rounded to the `Double/MIN_VALUE` or `0.0`, whichever is closer.

• The smallest double is `4.9e-324`. The value being tested is about twice that, so it would parse correctly anyway (it gets rounded to `1.0E-323`)

All of this is hidden because the wrong function was being called, which returns `nil` for invalid input.

Proposal:

• Test that numbers too large are rounded to Infinity.

• Test that numbers too small are rounded up to `Double/MIN_VALUE` or down to `0.0`.

• Test that strings that do not form valid doubles will return `nil` when parsed.
