[chuck-users] Std.atoi broken?

[Spencer Salazar]

Hi Atte,
Std.atoi comes from the C standard library atoi, which converts a  
string of ASCII characters into the represented integer if possible.   
So the domain of the function is the of set strings like "1", "200",  
"32768", etc., for which the return value would be 1, 200, 32768,  
etc.  Since "a" doesn't represent an integer (in base ten) it just  
returns 0 in that case.  Std.itoa, which is available but not  
documented, takes an integer like 1, 200, or 32768 and returns "1",  
"200", or "32768".

As far as getting the ASCII value of a character in a string, I don't  
believe there is a good way of doing that yet.  It should be possible  
to do once chuck's support of string operations is implemented, and  
that is something high on the priority list.

The only way I can think to do this right now in chuck is to build an  
associative array, associating each single character string with its  
ASCII value by hand.

hope this helps,
spencer
