Math |Hugo

Hugo provides nine mathematical operators in templates.

Function	Description	Example
`add`	Adds two numbers.	`{{add 1 2}}` → `3`
	If one of the numbers is a float, the result is a float.	`{{add 1.1 2}}` → `3.1`
`sub`	Subtracts two numbers.	`{{sub 3 2}}` → `1`
	If one of the numbers is a float, the result is a float.	`{{sub 3 2.5}}` → `0.5`
`mul`	Multiplies two numbers.	`{{mul 2 3}}` → `6`
	If one of the numbers is a float, the result is a float.	`{{mul 2 3.1}}` → `6.2`
`div`	Divides two numbers.	`{{div 6 3}}` → `2`
		`{{div 6 4}}` → `1`
	If one of the numbers is a float, the result is a float.	`{{div 6 4.0}}` → `1.5`
`mod`	Modulus of two integers.	`{{mod 15 3}}` → `0`
`modBool`	Boolean of modulus of two integers. Evaluates to `true` if result equals 0.	`{{modBool 15 3}}` → `true`
`math.Ceil`	Returns the least integer value greater than or equal to the given number.	`{{math.Ceil 2.1}}` → `3`
`math.Floor`	Returns the greatest integer value less than or equal to the given number.	`{{math.Floor 1.9}}` → `1`
`math.Round`	Returns the nearest integer, rounding half away from zero.	`{{math.Round 1.5}}` → `2`
`math.Log`	Returns the natural logarithm of the given number.	`{{math.Log 42}}` → `3.737`
`math.Sqrt`	Returns the square root of the given number.	`{{math.Sqrt 81}}` → `9`
`math.Pow`	Returns the first number raised to the power of the second number.	`{{math.Pow 2 3}}` → `8`
