- Use `ParseInt32`, `ParseInt64`, `ParseUInt32`, `ParseUInt64`, `ParseDouble` from `utilstrencodings.h` for number parsing
- *Rationale*: These functions do overflow checking, and avoid pesky locale issues
- *Rationale*: These functions do overflow checking, and avoid pesky locale issues.
- Avoid using locale dependent functions if possible. You can use the provided
[`lint-locale-dependence.sh`](/contrib/devtools/lint-locale-dependence.sh)
to check for accidental use of locale dependent functions.
- *Rationale*: Unnecessary locale dependence can cause bugs that are very tricky to isolate and fix.
- These functions are known to be locale dependent:
