STRTOD(3)           Linux Programmer's Manual           STRTOD(3)
+

+
+
NAME
+
       strtod - convert ASCII string to double
+
+
SYNOPSIS
+
       #include <stdlib.h>
+
+       double strtod(const char *nptr, char **endptr
+
+
DESCRIPTION
+
       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.
+
+
RETURN VALUES
+
       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.
+
+
ERRORS
+
       ERANGE Overflow or underflow occurred.
