Types

type Namespace

type Namespace struct{}

Namespace provides template functions for the "math" namespace.

func New

func New() *Namespace

New returns a new instance of the math-namespaced template functions.

func (*Namespace) Abs

func (ns *Namespace) Abs(n any) (float64, error)

Abs returns the absolute value of n.

func (*Namespace) Add

func (ns *Namespace) Add(inputs ...any) (any, error)

Add adds the multivalued addends n1 and n2 or more values.

func (*Namespace) Ceil

func (ns *Namespace) Ceil(n any) (float64, error)

Ceil returns the least integer value greater than or equal to n.

func (*Namespace) Counter

func (ns *Namespace) Counter() uint64

Counter increments and returns a global counter. This was originally added to be used in tests where now.UnixNano did not have the needed precision (especially on Windows). Note that given the parallel nature of Hugo, you cannot use this to get sequences of numbers, and the counter will reset on new builds. <docsmeta>{"identifiers": ["now.UnixNano"] }</docsmeta>

func (*Namespace) Div

func (ns *Namespace) Div(inputs ...any) (any, error)

Div divides n1 by n2.

func (*Namespace) Floor

func (ns *Namespace) Floor(n any) (float64, error)

Floor returns the greatest integer value less than or equal to n.

func (*Namespace) Log

func (ns *Namespace) Log(n any) (float64, error)

Log returns the natural logarithm of the number n.

func (*Namespace) Max

func (ns *Namespace) Max(inputs ...any) (maximum float64, err error)

Max returns the greater of the multivalued numbers n1 and n2 or more values.

func (*Namespace) Min

func (ns *Namespace) Min(inputs ...any) (minimum float64, err error)

Min returns the smaller of multivalued numbers n1 and n2 or more values.

func (*Namespace) Mod

func (ns *Namespace) Mod(n1, n2 any) (int64, error)

Mod returns n1 % n2.

func (*Namespace) ModBool

func (ns *Namespace) ModBool(n1, n2 any) (bool, error)

ModBool returns the boolean of n1 % n2. If n1 % n2 == 0, return true.

func (*Namespace) Mul

func (ns *Namespace) Mul(inputs ...any) (any, error)

Mul multiplies the multivalued numbers n1 and n2 or more values.

func (*Namespace) Pow

func (ns *Namespace) Pow(n1, n2 any) (float64, error)

Pow returns n1 raised to the power of n2.

func (*Namespace) Round

func (ns *Namespace) Round(n any) (float64, error)

Round returns the integer nearest to n, rounding half away from zero.

func (*Namespace) Sqrt

func (ns *Namespace) Sqrt(n any) (float64, error)

Sqrt returns the square root of the number n.

func (*Namespace) Sub

func (ns *Namespace) Sub(inputs ...any) (any, error)

Sub subtracts multivalued.
