Description

What is changing?

Is there new documentation needed for these changes?

What is the motivation for this change?

Release Highlight

Long.fromString takes radix into account before coercing '+/-Infinity' and 'NaN' to Long.ZERO

Long.fromString no longer coerces the following cases to Long.ZERO when the provided radix supports all characters in the string:

  • '+Infinity', '-Infinity', or 'Infinity' when 35 <= radix <= 36
  • 'NaN' when 24 <= radix <= 36
// when writing in radix 27, 'n' and 'a' are valid characters, so 'NaN' represents the decimal number 17060
Long.fromString('NaN', 27); // new Long(17060)
Long.fromString('NaN', 10); // new Long(0) <-- Since 'NaN' is not a valid input in base 10, it gets coerced to Long.ZERO

Double check the following

  • Ran npm run check:lint script
  • Self-review completed using the steps outlined here
  • PR title follows the correct format: type(NODE-xxxx)[!]: description
    • Example: feat(NODE-1234)!: rewriting everything in coffeescript
  • Changes are covered by tests
  • New TODOs have a related JIRA ticket
