+<h3>STRTOD(3) Linux Programmer's Manual STRTOD(3)
+</h3>
+
+<h3>NAME
+</h3> strtod - convert ASCII string to double
+
+<h3>SYNOPSIS
+</h3> #include &lt;stdlib.h&gt;
+
+ double strtod(const char *nptr, char **endptr
+
+<h3>DESCRIPTION
+</h3> The strtod function converts the initial portion of the
+ string pointed to by nptr to double representation.
+
+ 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.
+
+ Leading white-space characters in the string (as defined
+ by the isspace(3) function) are skipped.
+
+<h3>RETURN VALUES
+</h3> The strtod function returns the converted value, if any.
+
+ If endptr is not NULL, a pointer to the character after
+ the last character used in the conversion is stored in the
+ location referenced by endptr.
+
+ If no conversion is performed, zero is returned and the
+ value of nptr is stored in the location referenced by
+ endptr.
+
+ If the correct value would cause overflow, plus or minus
+ HUGE_VAL is returned (according to the sign of the value),
+ and ERANGE is stored in errno. If the correct value would
+ cause underflow, zero is returned and ERANGE is stored in
+ errno.
+
+<h3>ERRORS
+</h3> ERANGE Overflow or underflow occurred.
