Puppet math

A puppet module with a few math functions. Purely written in native puppet code.

This library might be useful in your code, but was created mostly for nerd sniping.

Functions

math::constants

Type: Puppet Language

The math::constants function.

math::constants(String $name)

The math::constants function.

Returns: Any

name

Data type: String

math::cube

Type: Puppet Language

Cubes a number

• Note puppet has a integer size limit so some values may not work and return a Puppet::ParseError

Examples

2

math::cube(2) => 8

3

math::cube(3) => 27

math::cube(Numeric $value)

The math::cube function.

Returns: Numeric

Examples

2

math::cube(2) => 8

3

math::cube(3) => 27

value

Data type: Numeric

math::exp

Type: Puppet Language

Produces a Integer that is an exponential power calculation on the provided value and power.

• Note puppet has a integer size limit so some values may not work and return a Puppet::ParseError

Examples

2^3

math::exp(2,3) => 8

2^8

math::exp(2,8) => 256

math::exp(Numeric $x, Integer[0,62] $y)

Produces a Integer that is an exponential power calculation on the provided value and power.

Returns: Numeric

Examples

2^3

math::exp(2,3) => 8

2^8

math::exp(2,8) => 256

x

Data type: Numeric

y

Data type: Integer[0,62]

math::fibonacci

Type: Puppet Language

Calculate the fibonacci sequence for the given number

• Note The input value maxes out at 27 because it takes too long to calclulate

math::fibonacci(Numeric $n, Enum[table,binet] $method = 'table')

The math::fibonacci function.

Returns: Integer

n

Data type: Numeric

method

Data type: Enum[table,binet]

math::fibonacci::binet

Type: Puppet Language

Calculate the fibonacci sequence for the given number using binet method

• Note The input value maxes out at 27 because it takes too long to calclulate

math::fibonacci::binet(Numeric $n)

The math::fibonacci::binet function.

Returns: Numeric

n

Data type: Numeric

math::fibonacci::table

Type: Puppet Language

Calculate the fibonacci sequence for the given number using table method

• Note The input value maxes out at 27 because it takes too long to calclulate

math::fibonacci::table(Numeric $n)

The math::fibonacci::table function.

Returns: Numeric

n

Data type: Numeric

math::round

Type: Puppet Language

rounds to the nearset decimal

math::round(Numeric $x)

The math::round function.

Returns: Numeric

x

Data type: Numeric

math::sqrt

Type: Puppet Language

returns the square root of the numeric value $x.

• Note This implementation uses Newton's method.

Examples

Square root of 9

math::sqrt(9) => 3

math::sqrt(Numeric $x)

The math::sqrt function.

Returns: Numeric

Examples

Square root of 9

math::sqrt(9) => 3

x

Data type: Numeric

math::square

Type: Puppet Language

Squares a number

• Note puppet has a integer size limit so some values may not work and return a Puppet::ParseError

Examples

2

math::square(2) => 4

3

math::square(3) => 9

math::square(Numeric $value)

The math::square function.

Returns: Numeric

Examples

2

math::square(2) => 4

3

math::square(3) => 9

value

Data type: Numeric

math::sum

Type: Puppet Language

Produces a Integer that is sum of all the numbers provided. Can take arrays or multiple values.

• Note puppet has a integer size limit so some values may not work and return a Puppet::ParseError

Examples

with array

math::sum([2,2,2]) => 6

without array

math::sum(2,2,2) => 6

math::sum(Variant[Numeric, Array[Numeric], Tuple] $value)

Produces a Integer that is sum of all the numbers provided. Can take arrays or multiple values.

Returns: Numeric

Examples

with array
