D - Why is there a 'char[] toString(uint u)' in the library and not a 'char[] toString(int i)'?

You make a valid point. I've had similar thoughts. I think we should add something like intToString as toString(int) to std.string. Hope this helps. /* by J C Calvarese License: Public Domain */ import std.string; import std.c.stdio; char[] intToString(int i) { if(i<0) return "-" ~ toString(cast(uint) -i); else return toString(cast(uint) i); } void main() { int j = -1604000; printf(intToString(j) ~ \n); j = 8_004_000; printf(intToString(j) ~ \n); } -- Justin http://jcc_7.tripod.com/d/

I don't think there is a way using just function_name(x) but there is
 format("%d",x)

would be nifty to have format overloaded:

 char[] format(int x) { return format("%d",x); }

etc etc

Hmm. what was that about a Phobos working group? Maybe I'll change my mind
that we don't need one. ;-)

That would highly inefficient, because of the parsing
of the format string made by format.

I like the way that you can do this in Java:

int i = 8;
String str = "" + i;

Phill.

 Phill.

Yup, the java way is nice (it could be more efficient though, a+b+c should be new StringBuffer(a).append(b).append(c).toString() rather than new StringBuffer(new StringBuffer(a).append(b).toString()).append(c).toString() ) Sort of related is the static String.valueOf method which can take any type (easy in java, just boolean, byte, char, short, int long, float, double, Object). Something like this would be useful for templates. Sam

Nope, phobos is. I'm adding it to the next release.
 How do I convert a simple int to a string?

Right now, sprintf() will have to do as a workaround.
