# Parses an input string using BigDecimal, it always expects a dot character as a decimal separator and
# generally does not accept other characters other than minus-hyphen and digits. It is useful for APIs, interop
# with other languages and other use cases where you expect well-formatted input and do not need to take user
# locale into consideration.
