Project Description

Javascript for basic website calculator. Need ASAP. Delivery will show script works in attached html and will provide all files.

Four formulas to calculate are:

1.) Roll Weight = Length * 12 * Width * Gauge / 3000000

2.) Roll Length = Weight * 3000000 / 12 * Width * Gauge

3.) Microns = Gauge * [url removed, login to view]

4.) Gauge = Microns / [url removed, login to view]


- Script should not calculate if an input field is empty or is not a numeric value. If the "calculate" button is pressed for the two formulas that have more than one input field, a basic error statment should be given (ex: "Enter a numeric value in fields above").

- Formula totals should round off to one decimal place (ex: [url removed, login to view] should round off to 123.5)

- Script should have comments to identify main functions

- Each calculator has a "calculate" and "clear" button

- If helpful there is a URL that has an example of some javascript working for a similar calculator, but do not want programmer to copy source. This job is to author own javascript solution to web tool requirements.
