I have created a simple calculator that will assist in creating magic items from the tabletop RPG Pathfinder. Here are the full requirements, and if you want a more concise version, here is a player generated summary of the process.I have been trying to get into F# and functional programming in general. I come from a strong object-oriented background and it has been difficult in ignoring those habits. Please focus on whether or not this is idiomatic F#. I would love to hear if there is a better way to write any of it. And, if you find bug, I'd be happy to know that too.QuestionsA couple of things specifically that I feel could be better would be the DC calculation. I wasn't sure how to approach applying the rush function only if the item was rushed. I also tried finding a place where I could apply functional composition, but I think I needed all the intermediate steps that I stop on.Codelet baseDC casterLevel =    5 + casterLevellet rush dc =    dc + 5let ignoreRequirements requirements dc =    dc + (5 * requirements)let getBuildPrice basePrice =    basePrice * 0.5let getTime basePrice =    floor (8.0 * basePrice / 1000.0)let getMinBonusForNoCursed dc =    dc - 6let buildDaysWhileAdventuring isRushed buildTime =    let adventuringBuildTime = buildTime / 4.0    floor (if isRushed then adventuringBuildTime else adventuringBuildTime * 2.0)[<EntryPoint>]let main argv =     printfn %A argv    let isRushed = true    let casterLevel = 1    let requirementsIgnored = 1    let basePrice = 5000.0    let buildPrice = getBuildPrice basePrice    let buildTime = getTime basePrice    let daysAdventuring = buildDaysWhileAdventuring isRushed buildTime    let DC =         match isRushed with        | false -> baseDC casterLevel |> ignoreRequirements requirementsIgnored        | true -> baseDC casterLevel |> ignoreRequirements requirementsIgnored |> rush    let minDC = getMinBonusForNoCursed DC    printfn Min/DC: %i/%i Cost: %.2f Days/Hours: %.1f/%.1f minDC DC        buildPrice daysAdventuring buildTime    0 // Return code
