Subject: Hexadecimal floating-point and strtod
Summary
C11 7.22.1.3 paragraph 3 bullet 2 says:
a0xor0X, then a nonempty sequence of hexadecimal digits optionally containing a decimal-point character, then an optional binary exponent part as defined in 6.4.4.2;
but the grammar in C11 6.4.4.2 makes the binary-exponent-part mandatory, not optional.
Suggested resolution
Strike "optional" before "binary exponent part" and add a comma before "as defined in" to highlight that "as defined in" applies to the entire sentence, not only to the last part.
