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. + +</pre> +<hr> +<h3>SEE ALSO +</h3><p> +<a href=atof.htm>atof</a>, +<a href=atoi.htm>atoi</a>, +<a href=atol.htm>atol</a>, +<a href=strtol.htm>strtol</a>, +<a href=strtoul.htm>strtoul</a>, +<pre> + +<h3>STANDARDS +</h3> The strtod function conforms to ANSI-C. + +<h3>BUGS +</h3> This is a BSD manual page and may not reflect the current + Linux implementation. + + + + + + +<h3>BSD Man Page 21 Aug 1994 1 +</h3> + +
