Use this rule to limit the permitted values for floating-point numbers. YAML permits three classes of float expressions: approximation to real numbers, positive and negative infinity and "not a number".

Parameters

require-numeral-before-decimal

Use require-numeral-before-decimal to require floats to start with a numeral (eg. 0.0 instead of .0).

forbid-scientific-notation

Use forbid-scientific-notation to forbid scientific notation.

forbid-nan

Use forbid-nan to forbid NaN (not a number) values.

forbid-inf

Use forbid-inf to forbid infinite values.

Examples

With float-values: {require-numeral-before-decimal: true} the following code snippets would PASS:

    anemometer:
      angle: 0.0

the following code snippets would FAIL:

    anemometer:
      angle: .0

With float-values: {forbid-scientific-notation: true} the following code snippets would PASS:

    anemometer:
      angle: 0.00001

the following code snippets would FAIL:

    anemometer:
      angle: 10e-6

With float-values: {forbid-nan: true} the following code snippets would FAIL:

    anemometer:
      angle: .NaN

With float-values: {forbid-inf: true} the following code snippets would FAIL:

    anemometer:
      angle: .inf
