Quick search showed that there is no well know scripting language that
has such function. C++/C# has this but they are not scripting
languages.
The following code does the same. Also we have to think about
BC(backward compatibility) with older scripts.
function sign($x){
return (int)((abs($x)-$x)? -1:$x>0);
}
Thank you for you suggestion.

The wonderful math-function list is missing a very important and simple
function: sign(). The is the comlpementof abs(), and together with
abs() allows you to separate the magnitude and sign of a number, e.g.
for graphing purposes (it's hard to graph a negative number of pixels,
and displaying money as "$-99" looks dumb).
It's a one-line function, so I've already written my own, but it really
ought to be built-in.
Thanks!
