To distinguish and determining the sign of a LR fuzzy number one can use from this function.
In other words, the function `sign`

is able to categorize the class of all LR fuzzy numbers into three kinds positive, negative and non of them (non-positive and non negative).

sign(M)
``` |

`M` |
A LR, RL or L fuzzy number |

The "sign" function only return three charactical values: "Positive", "Negative" or "non-positive and non negative".

Left.fun = function(x) { (1-x)*(x>=0)}
M = L(2,4,3)
support(M)
sign(M)
sign( L(5,4,3) )
( sign( L(5,4,3) ) == "Positive" )
## The function is currently defined as
function (M)
{
supp = support(M)
if (supp[1] > 0) {
return(noquote(paste0("Positive")))
}
else {
if (supp[2] < 0) {
return(noquote(paste0("Negative")))
}
else {
return(noquote(paste0("non-positive and non negative")))
}
}
