Description
Operators to return the larger or smaller of two values.
a<>b, compares 'a' and 'b', returns the larger of them
a><b, compares 'a' and 'b', returns the smaller of them
Examples
Simple larger examples
x=a<>b -- faster than x=math.max(a,b)
x=(x-1)<>5 -- decrement x, but don't go below 5
Simple smaller examples
x=a><b -- faster than x=math.min(a,b)
x=(x+1)><15 -- increment x, but don't go above 15
Make sure x is within bounds example
x=(x<>min)><max
Always return the negative of a number
x=-x><x -- faster than -math.abs
Always return the positive of a number
x=-x<>x -- faster than math.abs
