Number

Number typed values are a number.

Numbers...

• are immutable, i.e. assigning to an number results in a copy of the original number
• can be passed in/out of ops via number parameters
• can be initialized via number initialization
• are coerced according to number coercion

Initialization

Number typed values can be constructed from a literal or templated number.

A templated number is a number which includes one or more variable-reference [string]. At runtime, each reference gets evaluated and replaced with it's corresponding value.

Initialization Example (literal)

Initialization Example (templated)

given:

• someNumber
  • is in scope
  • is type coercible to number

# $(someNumber) replaced w/ someNumber
222$(someNumber)3e10

Coercion

Number typed values are coercible to:

• boolean (numbers which are 0 coerce to false; all else coerce to true)
• file
• string

Coercion Example (number to file)

name: numAsFile
run:
  container:
    image: { ref: alpine }
    cmd:
    - sh
    - -ce
    - cat /numCoercedToFile
    files:
      /numCoercedToFile: 2.2
