Number

Background

Given a file named “pen.json” with:

{
  "type": "library",
  "dependencies": {}
}

Use a number literal

Given a file named “Foo.pen” with:

f = \() number {
  42
}

When I run pen build

Then the exit status should be 0.

Use arithmetic operators

Given a file named “Foo.pen” with:

f = \() number {
  1 + 2 - 3 * 4 / 5
}

When I run pen build

Then the exit status should be 0.

Use equality operators

Given a file named “Foo.pen” with:

f = \() boolean {
  0 == 0
}

g = \() boolean {
  0 != 0
}

When I run pen build

Then the exit status should be 0.

Use order operators

Given a file named “Foo.pen” with:

f = \() boolean {
  0 < 0
}

g = \() boolean {
  0 <= 0
}

h = \() boolean {
  0 > 0
}

i = \() boolean {
  0 >= 0
}

When I run pen build

Then the exit status should be 0.
