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(N1,N2) | |
*Subtract | Subtract two values, x - y. | subtract(N1,N2) | |
*Multiply | Multiply two or more values, x * y. | multiply(N1,N2) | |
*Divide | Divide two values, x / y. | divide(N1,2) | |
*Power | Calculates the power of x to y, x ^ y. | pow(N1,2) | |
*Square | Compute the square of a value, x * x. | square(N1) | |
Square root | Calculate the square root of a value. | sqrt(N1) | |
Round | Round a value towards the nearest integer. | round(N1,2) | |
Round - Floor | Round a value towards minus infinity. | 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(N1) | |
Max | Compute the maximum value of a matrix or a list with values. | max(N1,N2,N3) | |
Min | Compute the minimum value of a matrix or a list of values. | min(N1,N2,N3) | |
Mean | Compute the mean value of matrix or a list with values. | mean(N1,N2,N3) | |
Median | Compute the median of a matrix or a list with values. | median(N1,N2,N3) | |
Mode | Computes the mode of a set of numbers or a list with values(numbers or characters). | mode(N1,N2,N3) | |
Standard deviation | Compute the standard deviation of a matrix or a list with values. | std(N1,N2,N3) | |
Sum | Compute the sum of a matrix or a list with values. | 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. |
