overflow
In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value.
The most common result of an overflow is that the least significant representable digits of the result are stored; the result is said to wrap around the maximum (i.e. modulo a power of the radix, usually two in modern computers, but sometimes ten or another radix).
An overflow condition may give results leading to unintended behavior. In particular, if the possibility has not been anticipated, overflow can compromise a program's reliability and security.
For some applications, such as timers and clocks, wrapping on overflow can be desirable. The C11 standard states that for unsigned integers modulo wrapping is the defined behavior and the term overflow never applies: "a computation involving unsigned operands can never overflow."On some processors like graphics processing units (GPUs) and digital signal processors (DSPs) which support saturation arithmetic, overflowed results would be "clamped", i.e. set to the minimum or the maximum value in the representable range, rather than wrapped around.
Thank-you all in advance.

Hi,
I've recently purchased a new property and need to replace the hot water system. The property only has electric and for simplicity I'm thinking of fitting a vented, direct water cylinder.
The overflow pipe on the current system comes through the bathroom wall and terminates just above the...

Hi I am new to the site and am looking for some help please
i have a baxi wm51/3rs boiler and when it is on there is hot water coming out the vent pipe back into the feed tank causing this to overflow, any ideas ?
Re. the overflow pipe: obv should enter the tank above max water level, but should the end of the pipe continue into the cistern and down below max water level? I've read this should be done to prevent draughts coming back along the pipe from outside. Is this correct?
The overflow pipe should...

Hi all.
I have just looked at a job where the customer requires a wc and basin fitted in an elderly relative's room 7meters away from the soil stack in the kitchen.
I have decided to fit a Sanitop macerator to pump the waste up to the ceiling and run 22mm pipe through the joists to the soil...
Working away up north at the moment in what must be the oldest Travelodge going! Anyway, went to have a shower earlier and I was showering away when an overflow elbow poking out of the tile low in the corner caught my eye. Have never seen this done before, was it sometimes the way before the...
I'm not sure if this is the correct forum as you will see below.

I was asked to buy a beige bowl and a half kitchen sink for a customer to replace his old Franke sink. I bought an Astracast and half way through fitting it I noticed there was no overflow so I rang Astracast and she said the smaller bowl was the overflow and said to tell the customer not to...
Hi there,
I was wondering if anyone knew weather or not an overflow/warning pipe connected to the CWSC and F&E tank in the loft needed to be insulated? Can't find anything in building regs or WRAS. I could be missing something though.
Thanks in advance :-)
Hey guys,
Recently managed to get shot of an awful bath I purchased stupidly from one of the DIY chains... now looking at some Carron ones.
There's so many baths with a curved end at the taps these days and the one thing that's bugging me crazy is how do people out there fit the overflow...
Can anyone help? A friend of mine has 2 CWSC in her loft. The two are linked by a 22mm pipe near the bottom of the tanks and both have independent float valves.
I'm told that the second tank was fitted to enable the installation of a shower pump?
Anyway, only 1 tank has an overflow which now...
Some dude has ran the waste from saniflo into rain water pipe and it's not a combined sewer. So I need to re do it and run pipes the opposite way to back of the house where soil is. So, old laminate floor up and run through joists. So I am thinking of using hep so no joints. I can see saniflo...
