= strtod =
== Syntax ==
:{{double strtod(const char* nptr, char** endptr)}}
== Arguments ==
:'''nptr'''
::Pointer to the string containing the value to convert.
:'''endptr'''
::Optional storage space for output by this function.
== Return ==
:The converted value from the string.
== Description ==
:This function will convert a string to a double value.
:The string is expected to have optional leading white space followed by an optional plus ('''+''') or minus ('''-''') character, any number of digits including a single decimal point and optionally an exponent which consists of either an '''E''' or '''e''', an optional plus or minus sign and one or more digits.
:If '''endptr''' is not NULL, a pointer to the next character after the parsed portion of the string is stored in the memory location reference by '''endptr'''.
:If the resultant value would overflow the boundaries of the double datatype, the maximum possible value is returned. If an underflow would occur, zero will be returned. In both cases an errorcode will be set which can be queried.
