FashiOne Multi Branch

Following the success of our single store version, we recently released a multi branch version of FashiOne.

Some New Features:

• Stock control multiple locations.
• Branch transfers.
• Remote back office client.
• Branch level pricing.

FashiOne Multi Branch is the second major release of our software.

FashiOne

As I have mentioned previously, I work for Mode Retail Ltd, which develops and sells a EPOS software specifically for the fashion industry.

Instead of creating a separate blog, I've decided to use my personal blog to talk about new features and maybe even provide sneak previews.

Date And Time In Programming

Lars has published a great article about the difficulties with date and time programming.

Vista takes 100+ YearsTo Copy Files

Marco Cantu has posted about Vista prediciting it will take over 100 years to copy some files.

Personally, I can't wait that long.

Implementing a Partial Serial Number Verification System in Delphi

Brandon Staggs has posted a excellent blog on writing a serial number verification system using Delphi.

The great thing is the techniques described can be applied to any language.

Calculating Discounts Part 2

I solved the problem in my Calculating Discounts post. Here is how it is done.

Variables
  ItemPrice = 50.00
  Discount  = 14.49%

Calculate Discount Value (DisValue)
  DisValue  = ItemPrice * (Discount/100)
  DisValue  = 50.00 * (14.49/100)
  DisValue  = 50.00 * 0.1449
  DisValue  = 7.245

Calculate NewPrice
  NewPrice  = ItemPrice - DisValue
  NewPrice  = 50.00 - 7.245
  NewPrice  = 42.755

Round Down Values
  NewPrice  = 42.75
  DisValue  =  7.24
  PriceDown = 49.99

Calculate CheckTotal
 CheckTotal = NewPrice + DisValue 
 CheckTotal = 42.75 + 7.24
 CheckTotal = 49.99

Calculate Missing Value
  MissValue = ItemPrice - CheckTotal 
  MissValue = 50.00 - CheckTotal 
  MissValue = 0.01

Add Missing Discount
  DisValue  = DisValue + MissValue 
  DisValue  = 7.25

Now the both the new price and the discount value will add up to the original price.

Calculating Discounts

Today we found an interesting bug in the software when discounts are applied to the transaction.

Here is an example.

Variables
  ItemPrice = 50.00
  Discount  = 14.49%

Calculate Discount Value (DisValue)
  DisValue  = ItemPrice * (Discount/100)
  DisValue  = 50.00 * (14.49/100)
  DisValue  = 50.00 * 0.1449
  DisValue  = 7.245

Calculate NewPrice
  NewPrice  = ItemPrice - DisValue
  NewPrice  = 50.00 - 7.245
  NewPrice  = 42.755

At this point we need to round the values, becuase prices have two decimal places. There are two options, we can either round the values up or down.

Round Up Values
  NewPrice = 42.76
  DisValue =  7.25
  Total    = 50.01 (1p over)

Round Down Values
  NewPrice = 42.75
  DisValue =  7.24
  Total    = 49.99 (1p under)

As you can see, when we add up the rounded totals, they do not match the original item price. So we need find a way to solve this problem.

Two Jobs

Yes I now have two jobs!

Mode is now its own company and I've just started part time in a support role. I may also do some occasional development work.

I don't know if I should revive my old blog.
