stdtod function in stdlib

[mmalcolm]

Hi everyone,<br><br>I am tying to use the &quot;stdtod&quot; that takes the first part of a string and makes it into a number (until it comes to a non-numeric character).&nbsp;&nbsp;I keep getting zero, no matter what the string is.&nbsp;&nbsp;here's my code:<br><br>&nbsp;<br>#include &lt;stdio.h&gt;<br>#include &lt;stdlib.h&gt;<br>#include &lt;string.h&gt;<br><br>void main() {<br><br> char input[] = &quot;23&quot;, *pEnd;<br> double number = 0.0;<br><br>// gets(input);<br> number = strtod(input, (char **)NULL);<br>// number = atof(input);<br> <br> printf(&quot;The input is %s\n&quot;, input);<br> printf(&quot;The number is %d&quot;, number);<br>}<br><br>//END OF CODE<br><br>As you can see, I've also tried the &quot;atof&quot; function but that did not help either.&nbsp;&nbsp;Can anyone help me fix this code?<br><br>Thanks,<br><br>Rio

actually their is already a funciton that does this to some extent it is called sprintf();&nbsp;&nbsp;I think you can do this to some extent.&nbsp;&nbsp;The other problem you might have is if you are bringing in a charecter say 0 that in integer will acutally be the ascii value of i tink 48 or something.&nbsp;&nbsp;You simply have to subtract the 0 ascii value to find the original value.<br><br>hope this helps i put something similar up on my website. <p>moses<br><a href=mailto:tmoses@iname.com>tmoses@iname.com</a><br><a href=

hi rio,<br><br>&nbsp;the function works fine. there is an error in your printf<br>statement. actually you are trying to print out a double<br>value using <b>%d</b>. try <b>%f</b> instead and your output will be<br>something like 23.000000.<br><br>-- ralf<br>
