+// FUNCTION
+// <<atof>>, <<atoff>>---string to double or float
+// INDEX
+// atof
+// INDEX
+// atoff
+// ANSI_SYNOPSIS
+//
+
+// #include <stdlib.h>
+// double atof(const char *<[s]>);
+// float atoff(const char *<[s]>);
+// TRAD_SYNOPSIS
+// #include <stdlib.h>
+// double atof(<[s]>)
+// char *<[s]>;
+// float atoff(<[s]>)
+// char *<[s]>;
+// <<atof>> converts the initial portion of a string to a <<double>>.
+// <<atoff>> converts the initial portion of a string to a <<float>>.
+// The functions parse the character string <[s]>,
+// locating a substring which can be converted to a floating point
+// value. The substring must match the format:
+// . [+|-]<[digits]>[.][<[digits]>][(e|E)[+|-]<[digits]>]
+// The substring converted is the longest initial
+// fragment of <[s]> that has the expected format, beginning with
+// the first non-whitespace character.  The substring
+// is empty if <<str>> is empty, consists entirely
+// of whitespace, or if the first non-whitespace character is
+// something other than <<+>>, <<->>, <<.>>, or a digit.
+// <<atof(<[s]>)>> is implemented as <<strtod(<[s]>, NULL)>>.
+// <<atoff(<[s]>)>> is implemented as <<strtodf(<[s]>, NULL)>>.
+// RETURNS
+// <<atof>> returns the converted substring value, if any, as a
+// <<double>>; or <<0.0>>,  if no conversion could be performed.
+// If the correct value is out of the range of representable values, plus
+// or minus <<HUGE_VAL>> is returned, and <<ERANGE>> is stored in
+// <<errno>>.
+// If the correct value would cause underflow, <<0.0>> is returned
+// and <<ERANGE>> is stored in <<errno>>.
+// <<atoff>> obeys the same rules as <<atof>>, except that it
+// returns a <<float>>.
+// PORTABILITY
+// <<atof>> is ANSI C. <<atof>>, <<atoi>>, and <<atol>> are subsumed by <<strtod>>
+// and <<strtol>>, but are used extensively in existing code. These functions are
+// less reliable, but may be faster if the argument is verified to be in a valid
+// range.
+// Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+// <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
