This is the code:
_h1 hello _p Lambdatalk can compute: {pre '{sqrt {+ {* 3 3} {* 4 4}}} -> {sqrt {+ {* 3 3} {* 4 4}}} } _p It's better to define a function {pre '{def hypo {lambda {:a :b} {sqrt {+ {* :a :a} {* :b :b}}}}} -> {def hypo {lambda {:a :b} {sqrt {+ {* :a :a} {* :b :b}}}}} } _p and to call it as much as we want. {pre '{hypo 3 4} -> {hypo 3 4} } {pre '{hypo 1 1} -> {hypo 1 1} } _p You are welcome! {style pre { padding:5px; box-shadow:0 0 8px #000; transform:rotate(-2deg); } }
