Showing the example using both a multipler function and currying:
<lang Axiom>(x,xi,y,yi) := (2.0,0.5,4.0,0.25);
(z,zi) := (x+y,1/(x+y));
(numbers,invers) := ([x,y,z],[xi,yi,zi]);
multiplier(a:Float,b:Float):(Float->Float) == (m +-> a*b*m);
[(multiplier(number,inver)) 0.5 for number in numbers for inver in invers];
[curryLeft(*$Float,number*inver) 0.5 for number in numbers for inver in invers]
</lang>Output:
<lang Axiom> [0.5,0.5,0.5]
Type: List(Float)</lang>
In comparison to using functions:
<lang Axiom>fns := [sin$Float, cos$Float, (x:Float):Float +-> x^3]
inv := [asin$Float, acos$Float, (x:Float):Float +-> x^(1/3)]
[(f*g) 0.5 for f in fns for g in inv]
</lang>
- which has the same output.
