Values

Umbra has various value types including strings (str), numbers (num), booleans (bool), etc. Here are a few basic examples.

Strings, which can be added together with +.

values.u

io::println("umbra" + "lang")

Numbers.

values.u

io::println("1+1 =", 1+1)
io::println("7/3 =", 7/3)

Booleans, with boolean operators as you’d expect.

values.u

io::println(true and false)
io::println(true or false)
io::println(!true)

$ umbra values.u
# umbralang
# 1+1 = 2
# 7/3 = 2.3333333333333335
# false
# true
# false
