<br>
A newbie question (I've tried for hours to figure this
out, but failed):<br>
<br>
I want to read a single character from a file, and have it
return the <br>
integer representation of the character. I've used:<br>
<br>
<a class="moz-txt-link-freetext" href="file:open(Fname">file:open(Fname</a>, [read, raw, binary]) to open the file and<br>
<a class="moz-txt-link-freetext" href="file:read(Fd,1)">file:read(Fd,1)</a> to retrieve a character.<br>
<br>
This works fine and I'll get back, for example
<<"%">>, which is_binary <br>
tells me is a binary. I've tried
binary_to_integer(<<"%">>) but I get a <br>
badarg error.<br>

<div>binary_to_integer converts the binary text
representation of an integer to an integer, i.e.
binary_to_integer(<<"123">>) -> 123.</div>

</div>
<div>To get the integer value of a binary you can either use
pattern matching as Dan suggestest:</div>

<div>or you can use
binary:decode_unsigned(<<"%">>) -> 37.</div>
