Hi all, I was wondering if anyone had any good recommendations for programming books for children. I want to get my son into programming as he shows an interest in it, but most books are a little dry due to the target market. I grew up using Usbourne books teaching Basic, with the book showing a listing and then various minor corrections for the BBC, Vic20, Apricot, Spectrum & CBM - which I then had to correct to make them work on an Amstrad CPC. However, these aren't really that viable these days... Anyway enough nostalgia - I'm not too fussed whether it is PHP, Java, C#, Python, etc. I do have a Raspberry Pi so I thought Python might be a good bet as he could transfer the programs from the laptop to the Pi. I must add that is a Windows 8 laptop, just in case that influences any answers. Apologies if this topic has already been covered in a thread elsewhere, but I couldn't find one talking about programming books. Any suggestions will be gratefully received.

I noticed some very stange values coming back from some calculations in a datatable and decided to investigate. Has anyone come across the problem below ?CSng(.51) + 0.01 0.51999999046325684 ?CSng(.57) + CSng(1) 1.56999993 I assume this is something to do with the way that the floating point value is held, but I've never seen it before. I'm using VB.NET to do this, but has anyone else noticed similar behaviour in other flavours of .NET? :confused:
