[newbie] from string to operator

ruby-talk
1

i’ve a script part like that :
[…]
case operand
when "+"
setNumber(getMemory + getNumber)
when "-"
setNumber(getMemory - getNumber)
when "*"
setNumber(getMemory * getNumber)
when "/"
setNumber(getMemory / getNumber)
end
[…]

is there a way to replace all the above with something like an eval
function :

eval(getMemory, operand, getNumber)

that’s to say a way to transform the string operand to the operator ???

getMemory.send(‘+’,getNumber)

Or use the “===” operator…
