52
53 o One of INF or INFINITY, ignoring case
54
55 o One of NAN or NAN(n-char-sequence(opt)), ignoring case in
56 the NAN part, where:
57
58 n-char-sequence:
59 digit
60 nondigit
61 n-char-sequence digit
62 n-char-sequence nondigit
63
64
65
66 In default mode for strtod(), only decimal, INF/INFINITY, and
67 NAN/NAN(n-char-sequence) forms are recognized. In C99/SUSv3 mode,
68 hexadecimal strings are also recognized.
69
70
71 In default mode for strtod(), the n-char-sequence in the NAN(n-char-
72 equence) form can contain any character except ')' (right parenthesis)
73 or '\0' (null). In C99/SUSv3 mode, the n-char-sequence can contain
74 only upper and lower case letters, digits, and '_' (underscore).
75
76
77 The strtof() and strtold() functions always function in
78 C99/SUSv3-conformant mode.
79
80
81 The subject sequence is defined as the longest initial subsequence of
82 the input string, starting with the first non-white-space character,
83 that is of the expected form. The subject sequence contains no
84 characters if the input string is not of the expected form.
85
86
87 If the subject sequence has the expected form for a floating-point
88 number, the sequence of characters starting with the first digit or the
89 decimal-point character (whichever occurs first) is interpreted as a
90 floating constant of the C language, except that the radix character is
91 used in place of a period, and that if neither an exponent part nor a
92 radix character appears in a decimal floating-point number, or if a

287 a. If +HUGE_VAL is returned and errno is set to ERANGE, a
288 floating point overflow occurred while processing a
289 positive value, causing a floating point overflow
290 exception to be raised.
291
292 b. If -HUGE_VAL is returned and errno is set to ERANGE, a
293 floating point overflow occurred while processing a
294 negative value, causing a floating point overflow
295 exception to be raised.
296
297 c. If strtod() does not set errno to ERANGE, the value
298 specified by the "subject string" converted to +HUGE_VAL
299 or -HUGE_VAL, respectively.
300 Note that if errno is set to ERANGE when strtod() is called, case
301 (c) can be distinguished from cases (a) and (b) by examining either
302 ERANGE or the overflow flag.
