Description


Operators to return the larger or smaller of two values.

a <> b   Compare 'a' and 'b', return the larger of them.
a >< b   Compare 'a' and 'b', return 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
