Using Angular and Typescript to implement mathematical formulas involving date object subtraction

I need help converting the following Excel formula to Typescript. I keep running into an error that says 'The left-hand and right-hand side of an arithmetic operation must be of type 'any', 'number' or an enum type'. Can anyone assist me with this?

const result = ((inceptionDate) - 365.25 - referenceInceptionDate) / 365.25 + (riskFactor))

Just a heads up, both inceptionDate and referenceInceptionDate are Date objects.

I tried the following code and it seemed to work without any errors. Can someone confirm if this is the correct approach?

const result: number = ((inceptionDate.valueOf() - 365.25 - entry.referenceInceptionDate.valueOf()) / 365.25 + (riskFactor));

Thank you!

Answer №1

When working with a date object, attempting calculations can be tricky since it is not a native numerical object. To overcome this issue, it's recommended to modify the code and utilize methods like valueOf().

Alternatively, if you anticipate performing numerous calculations involving dates, incorporating a specialized date library like Moment.js might prove beneficial.
