if true
    println("It's true!")
else
    println("It's false!")
end
#> It's true!

if false
   println("It's true!")
else
   println("It's false!")
end
#> It's false!

# Numbers can be compared with opperators like <, >, ==, !=

1 == 1.
#> true

1 > 2
#> false

"foo" != "bar"
#> true

# and many functions return boolean values

occursin("that", "this and that")
#> true

# More complex logical statments can be achieved with `elseif`

function checktype(x)
   if x isa Int
      println("Look! An Int!")
   elseif x isa AbstractFloat
      println("Look! A Float!")
   elseif x isa Complex
      println("Whoa, that's complex!")
   else
      println("I have no idea what that is")
   end
end

checktype(2)
#> Look! An Int!

checktype(√2)
#> Look! A Float!

checktype(√Complex(-2))
#> Whoa, that's complex!

checktype("who am I?")
#> I have no idea what that is

# For simple logical statements, one can be more terse using the "ternary operator".........完整代码请登录后点击上方下载按钮下载查看
