1. Missing abs() in Euphoria?
Hi all,
Unless I overlooked it, it seems that Euphoria doesn't have a "abs()"
function to get the absolute value of a number... Of course it is very easy
to implement, but you should expect this to be a standard function in any
language..
Kind regards
Eddy

Hi Eddy,
Yes, you are correct, there is no abs() function.
There has been considerable discussion over this on the list in the past.
The last mention I heard of it was at:
&H=0&O=D&T=1&m=20974
and quoted the function:
>The 'sequence-magic' abs() function is:

>function abs(object x)
> -- The bit in the outer brackets is normally in the function "sgn()"
> return x * ( (x>0)-(x<0) )
>end function

Ray,
Carl's abs function is quite elegant, but the one below, proposed by
Pete, is generally faster. jiri
function abs(object x)
object temp
if atom(x) then
if x<0 then return -x else return x end if
end if
for i=1 to length(x) do
temp = x[i]
if atom(temp) then
if temp<0 then x[i]=-temp end if
else
x[i]=abs(temp)
end if
end for
return x
end function
