TKF15H has it. first you are negating the random number, then turning it into a string. EZ

take away its result from (itself x2).

result = 4
rev = (result-(result*2))

print result
print rev
sync
suspend for key
end

or simply

damage$ = STR$(0-damage#)

or

damage$ = STR$(sqrt(1)*(0-((asin(sin(sqrt(abs(damage#)^2))))&(asin(sin(sqrt(abs(damage#)^2)))))))

hahaha.
That is one slow peace of code! lets take a look at that:

First you got the string, no problem there,

then you got the square of 1 (which is 1) and multiplied it by the stuff after it...(in other words you did nothing)

with the 0-... you made the number a negative. OK.

then the asin of the sin. Thats funny. I never thought about that one. It probably just returns the same value it had before.

then you got the square root of the following value times it self. (in other words you did nothing)

Nice code!! :-d

ABS gives you the ABSolute value of a value - in other words, it removes the sign, (as Drifter said).

ABS(-34) = 34

It's use is mainly when you want to find out the difference between two values and you don't know which is the larger.

X=300
Y=200
Diff=X-Y ... Diff = 100

But if:

X=200
Y=300
Diff=X-Y ... Diff = -100

Using Diff=ABS(X-Y) means you always get a positive difference value - regardless of the size of the two values.

How about:
damage$="-"+str$(damage#)

There are so many ways!

actually kevil that will only work if he doesn't actually need the variable to be a negative number. if ya do it that way it just appears to be negative and it is in fact positive

And if damage$ is already negative (lets say -1) I think you'll get: "--1"
