Logic Syntax

This is a short list of the most commonly used functions.

These functions can be used in any logic field in CheckFirst.

Functions marked with * are also available in an operator format.

Function name	Description	Function	Example
*Add	Add two or more values, x + y.	add(x, y)	add(N1,N2)
*Subtract	Subtract two values, x - y.	subtract(x, y)	subtract(N1,N2)
*Multiply	Multiply two or more values, x * y.	multiply(x, y)	multiply(N1,N2)
*Divide	Divide two values, x / y.	divide(x, y)	divide(N1,2)
*Power	Calculates the power of x to y, x ^ y.	pow(x, y)	pow(N1,2)
*Square	Compute the square of a value, x * x.	square(x)	square(N1)
Square root	Calculate the square root of a value.	sqrt(x)	sqrt(N1)
Round	Round a value towards the nearest integer.	round(x,n)	round(N1,2)
Round - Floor	Round a value towards minus infinity.	floor(x)	floor(N1)
Round - Ceiling	Round a value towards plus infinity. If x is complex, both real and imaginary parts are rounded towards plus infinity.	ceil(x)	ceil(N1)
Max	Compute the maximum value of a matrix or a list with values.	max(a, b, c, …)	max(N1,N2,N3)
Min	Compute the minimum value of a matrix or a list of values.	min(a, b, c, …)	min(N1,N2,N3)
Mean	Compute the mean value of matrix or a list with values.	mean(a, b, c, …)	mean(N1,N2,N3)
Median	Compute the median of a matrix or a list with values.	median(a, b, c, …)	median(N1,N2,N3)
Mode	Computes the mode of a set of numbers or a list with values(numbers or characters).	mode(a, b, c, …)	mode(N1,N2,N3)
Standard deviation	Compute the standard deviation of a matrix or a list with values.	std(a, b, c, …)	std(N1,N2,N3)
Sum	Compute the sum of a matrix or a list with values.	sum(a, b, c, …)	sum(N1,N2,N3)
If/Else	Executes an action if a condition is met (true) and another action if that condition is not met (false).	ifelse(conditions,then,else...)	ifelse((O1>1) and (O2>1),true,false) ifelse(O1>
Count if	Count the number of elements that fulfil a condition.	countif([Range],condition)	countif([O1,O2,O3], "Correct")
Round	Round a number x to n decimal place	round(x,n)	round(O2,3) round the numeric output of logic O2 to 3 decimal places.
