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) Acos ¶

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

Acos returns the arccosine, in radians, 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) Asin ¶

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

Asin returns the arcsine, in radians, of n.

func (*Namespace) Atan ¶

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

Atan returns the arctangent, in radians, of n.

func (*Namespace) Atan2 ¶

func (ns *Namespace) Atan2(n, m any) (float64, error)

Atan2 returns the arc tangent of n/m, using the signs of the two to determine the quadrant of the return value.

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) Cos ¶

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

Cos returns the cosine of the radian argument 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 all numbers in inputs. Any slices in inputs are flattened.

func (*Namespace) Min ¶

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

Min returns the smaller of all numbers in inputs. Any slices in inputs are flattened.

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) Pi ¶

func (ns *Namespace) Pi() float64

Pi returns the mathematical constant pi.

func (*Namespace) Pow ¶

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

Pow returns n1 raised to the power of n2.

func (*Namespace) Product ¶

func (ns *Namespace) Product(inputs ...any) (product float64, err error)

Product returns the product of all numbers in inputs. Any slices in inputs are flattened.

func (*Namespace) Rand ¶

func (ns *Namespace) Rand() float64

Rand returns, as a float64, a pseudo-random number in the half-open interval [0.0,1.0).

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) Sin ¶

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

Sin returns the sine of the radian argument n.

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.

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

Tan returns the tangent of the radian argument n.

func (*Namespace) ToDegrees ¶

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

ToDegrees converts radians into degrees.

func (*Namespace) ToRadians ¶

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

ToRadians converts degrees into radians.
