Function call operators

== Synopses

Declared in `<bslfmt_formatterspecificationnumericvalue.h>`

Throw an exception of type `format_error`. This indicates visitation of a `bsl::format` argument of boolean type, usually resulting from a user error such as calling `bsl::format("{:{}}", value, b)` where `b` is `bool`.

Throw an exception of type `format_error`. This indicates visitation of an argument with no value, which would indicate a logic error. Note that this would only be called when extracting a value from a `basic_format_arg` that holds no value, which would normally indicate an incorrect argument type.

Throw an exception of type `format_error`. This indicates visitation of a `bsl::format` argument of non‐integral type, usually resulting from a user error such as calling `bsl::format("{:{}}", value, f)` where `f` has a floating point type.
