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

<br /> 
x=a&lt;&gt;b -- faster than x=math.max(a,b)
x=(x-1)&lt;&gt;5 -- decrement x, but don't go below 5

Simple smaller examples

<br /> 
x=a&gt;&lt;b -- faster than x=math.min(a,b)
x=(x+1)&gt;&lt;15 -- increment x, but don't go above 15

Make sure x is within bounds example

<br /> 
x=(x&lt;&gt;min)&gt;&lt;max

Always return the negative of a number

<br /> 
x=-x&gt;&lt;x -- faster than -math.abs

Always return the positive of a number

<br /> 
x=-x&lt;&gt;x -- faster than math.abs
