Hello I've been asked to help out with Yr13 Computer Science - alas my theory is "rusty" to say the least. I've followed an example; all numbers below use the last 4 bits as the exponent: 0110 00 0001 - 0101 00 0010 after transforming the 'first' float to have a common exponent of 2 (giving 0011 00 0010), apply Two's complement to the second number (1011 00 0010) to make it negative so that we can "add" a positive and a negative to do subtraction, the example gets 1110 00 0010 as an answer, which I agree with; if we apply Two's complement and convert back we would get an answer of -1 in denary, which is correct. However, the example takes 1110 00 0010 and "normalises" it... fine, I can see we need to shift the Mantissa two columns and adjust the exponent accordingly, this gives: 1000 00 0000 which I 'agree' with with the proposed Normalisation. Problem: how on earth does 1000 00 0000 map to the 'correct' answer of -1 for the subtraction? No matter what I do, I can't get it to convert to -1 in denary. Clearly applying "Two's complement" to this negative binary as first step just yields the same thing back again. Any ideas what I'm missing as to how the final answer equates to -1? Thanks to anyone who can remember this stuff

For any future readers, I managed to achieve this but it was not easy and most of the work had to be done in Excel with a lot of assumptions and inferences. I found a report in SIMS that outputted columns Full Name Staff Code Class Period Period Date Period Times Cover Staff Code Cover Staff Name Cover Date Cover Times Cover Type From this I was able to extract a list of cover staff (starting staff code $...) and the time(s) they had covered lesson on each date. From this, I was able to calculate the cumulative length of lessons they covered per day and with some crude logic I decided anything more than 3.5 hours was a 'full day' and anything less would probably have been a 'half day' shift. From this I could then generate total number of cover staff man-days worked per period and apply a crude day rate average to calculate cost. It was a pain.

Hello, thanks for your reply. I had seen that feature but on my system it returns fields Staff Code, Staff Name, No. of Assignments, Total Credited Time, Weighted time. The counts for a given supply staff show the total number of "assignments" (lessons) between two dates but it's not clear how this relates to days worked. I'm trying to work out how many days each $Supply did so I can try to do like-for-like cost comparison. Does your SIMS return different fields on that report?

Hello We use SIMS for cover and I would like to pull some data about cover out of SIMS for analysis eg in Excel. Trying to do a comparison in our use of external cover (cover supervisors and teachers) between dates X&Y versus dates A&B. Interested in generating a report that would give me date, name, hours worked (interested in working out if full or half day), role, so that I can work out comparative stats for "man days of external cover supervisors booked between date X and Y", "man days of external supply teachers booked between date X and Y" versus competing dates, etc Has anyone got any pointers on how I would get such a report out of SIMS? I've had a look at the Report Design and it doesn't seem to have any of the options I'm after... thanks in advance for any help

Thanks for the replies; using the link from psydii, the article gave me some good ideas and we've ended up using OneNote via OneDrive - really great functionality and exactly what we needed.

Thanks for this, good link

Was hoping to do things like tagging, summary statistics. How many kids have achieved award X, or Y? Also, 'click to print' to generate paper copies of everything ,etc

Hello We've been tasked with creating an electronic equivalent of the old "record of achievement" folders kids used to complete back in the '90s.... everything from merit certificates to swimming badges to Duke of Edinburgh's award etc.... Anyone know of any good platforms that would do this? Particularly interested in single-sign-on (Microsoft/Azure environment)... thanks in advance
