Numeric Equation Functions

This article will provide the numeric equation field functions available to use and their definitions.

Notes:

The functions listed in this article are only available for equation fields. If you're looking for the functions available for text formula fields, see our article here.
The equation type must be set to "numeric" to use most of these functions.
Functions such as min and max can also be used in Date Equations.

Many regular math functions (such as "ceil" or "max") can be used in Knack numeric equations. Others, such as getDateDayOfMonth provide numeric values for a date.

Name	Description	Example with Result
`abs`	Calculates the absolute value of a number	abs(3.85) = 4
`cbrt`	Calculate the cube root of a number	cbrt(27) = 3
`ceil`	Round a value up to the nearest integer	ceil(4.2) = 5
`cos`	Calculate the cosine of a number	cos(2) = -0.4161468365471424
`factorial`	Compute the factorial of a number	factorial(5) = 120
`floor`	Round a value down to the nearest integer	floor(2.8) = 2
`gcd`	Calculate the greatest common denominator of a comma-separated list of numbers	gcd(5, 25) = 5
`log`	Calculate the logarithm of a number. The first number is the value for which to calculate, the second is the base.	log(10,4) = 1.6609640474436813
`log10`	Calculate a base 10 logarithm. Same as log(x, 10)	log10(4) = 0.6020599913279623
`max`	Get the maximum of a comma-separated list of values	max(1,6,9) = 9
`mean`	Compute the mean of a list of values	mean(1,6,8) = 5
`median`	Compute the median of a list of values	median(8,9,1) = 8
`min`	Get the minimum of a list of values	min(43,100,3) = 3
`pow`	Calculate the base to the exponent power	pow(7,2) = 49
`random`	Get a random number between two values	random(1,42) = 36.238172
`randomInt`	Get a random integer within a specified range. Please note that the returned value can be inclusive of the first integer but exclusive of the second integer listed in the parentheses.	randomInt(1,42) = 36 (Possible values returned can be 1-41.)
`round`	Rounds the first number to the precision of the second number	round(5.5,3) = 6
`sign`	Calculate the sign of a number: -1 if the number is less than 0, 1 if the number is greater than 0, 0 if the number is 0	sign(2) = 1
`sin`	Calculate the sine of a number	sin(15) = 0.6502878401571168
`std`	Compute the standard deviation of a list of values	std(1,5,42,78) = 36.07861785970558
`sqrt`	Calculate the square root of a number	sqrt(81) = 9
`sum`	Compute the sum of a list of values	sum(1,42,56) = 99
`tan`	Calculate the tangent of a number	tan(16) = 0.3006322420239034
`var`	Compute the variance of a list of values	var(1,42,34,67) = 742
`netWorkDays`	Get the number of working/business days between two dates	netWorkDays(06/18/2018,06/27/2018) = 7

Note: The netWorkDays function calculates the total number of working days between two dates, considering only Monday to Friday.

If your dates include time, it does not take into account working hours (e.g. 9 am-5 pm). The function only will count for a full 24-hour day.

The following examples use April 15, 2017, as the date:

`getDateDayOfWeek`	Get the numeric day of the week from a Date (Sunday = 1)	getDateDayOfWeek({Date}) = 7
`getDateDayOfMonth`	Get the numeric day of the month from a Date	getDateDayOfMonth({Date}) = 15
`getDateWeek`	Get the numeric week of the year from a Date	getDateWeek({Date}) = 15
`getDateMonth`	Get the numeric month from a Date	getDateMonth({Date}) = 4
`getDateQuarter`	Get the numeric quarter from a Date	getDateQuarter({Date}) = 2
`getDateYear`	Get the numeric year from a Date	getDateYear({Date}) = 2017
