-The expected form of the string
-is an optional plus (``+'') or minus (``\-'') sign,
-followed by either:
-.Bl -bullet
-.It
-a decimal significand, consisting of a sequence of decimal digits
-(optionally containing a decimal-point character) or
-.It
-a hexadecimal significand, consisting of a ``0X'' or ``0x'' followed
-by a sequence of hexadecimal digits
-(optionally containing a decimal-point character).
-.El
+The expected form of the string is an optional plus (``+'') or minus
+sign (``\-'') followed by a sequence of digits optionally containing
+a decimal-point character, optionally followed by an exponent.
+An exponent consists of an ``E'' or ``e'', followed by an optional plus
+or minus sign, followed by a sequence of digits.
 .Pp
-In both cases, the significand may be optionally followed by an
-exponent.
-An exponent consists of an ``E'' or ``e'' (for decimal
-constants) or a ``P'' or ``p'' (for hexadecimal constants),
-followed by an optional plus or minus sign, followed by a
-sequence of decimal digits.
-For decimal constants, the exponent indicates the power of 10 by
-which the significand should be scaled.
-For hexadecimal constants, the scaling is instead done by powers
-of 2.
-.Pp
-Alternatively, if the portion of the string following the optional
-plus or minus sign begins with ``INFINITY'' or ``NAN'', ignoring
-case, it is interpreted as an infinity or a quiet NaN, respectively.
-.Pp
-In any of the above cases, leading white-space characters in the
-string (as defined by the
+Leading white-space characters in the string (as defined by the
