The simplest is
diff = (new_angle-old_angle + 360) mod 360
You will have to decide if you want negative results or all positive. It depends on the usage.
MOD gives integer results so either multiply by 10 then MOD then divide by 10 etc or use another way to do MOD
dim float old_angle, new_angle, diff
do
input "both angles:", old_angle,new_angle
diff = (new_angle-old_angle + 360) mod 360 ' MOD gives integer results
print diff
diff = new_angle-old_angle + 360
if diff >= 360 then diff = diff - 360
print diff
print
loop
do
input "both angles:", old_angle,new_angle
diff = (new_angle-old_angle + 360) mod 360 ' MOD gives integer results
print diff
diff = new_angle-old_angle + 360
if diff >= 360 then diff = diff - 360
print diff
loop
edit:
diff = (((new_angle-old_angle)*10 + 3600+1800) mod 3600)/10-180 ' 1 decimal place and negatives
