• Conditional Statements: Provides logic-based outcomes based on conditions.

Example: if(10>5) {55} else {66}

• [qty]: Returns the Bill Item Quantity, changing this will affect the total quantity.

JavaScript Math Functions

These functions utilize JavaScript to perform more advanced mathematical calculations.

• Math.E: Euler’s constant, approximately 2.718.

 

• Math.LN(): Natural logarithm

Example: Math.LN(2) Natural logarithm of 2, approximately 0.693

• Math.log(): Natural logarithm of a number.

Example: Math.log(2)

• Math.LOG()E: Example: Base 2 logarithm of E, approximately 1.443.

 

• [PI] or Math.PI: The mathematical constant π, approximately 3.14159.

 

• Math.ceil(): Rounds a number up to the nearest integer.

Example: Math.ceil(2.1)will round up to 3

• Math.floor(): Rounds a number down to the nearest integer.

Example: Math.floor(2.9)will round down to 2

• Math.min(): Returns the smallest value in a list of arguments.

 Example: Math.min(0, 150, 30, -200, -8, -200) will give -200

• Math.max(): Returns the largest value in a list of arguments.

Example: Math.max(0, 150, 30, 20, -8, -200) will give 150

• Math.SQRT(x):  Square root of number.

Example: Math.SQRT(2) Square root of 2, approximately 1.414

• Math.round(x) - Rounds a number.

 

• x.toFixed(2) - Rounds a number to two decimal places.

 

• Math.sin(x) - Calculates the sine value.

JavaScript Date Functions - Contract Duration & Variables

Date calculations can also be performed using appropriate syntax. These functions help manage contract-related calculations based on dates.

• Contract Start Date: Define the start date for the contract.

 Example: SD1 is 10/01/2017

• Contract End Date: Define the end date for the contract.  

Example: ED1 is 24/05/2017

• Contract Duration: Calculate the duration of the contract.

Example: CD1 = (([ED1]-[SD1])/1000/60/60/24/365.242*12*4.33).toFixed(2) will make the final duration 19.07 weeks
