overflowing
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.
Hi. been called to a job with a leaking tundish, never touch these things and wondered how to go about changing it. Looks like 2 22ml comp fittings either end of the tundish, is it just a case of undoing both ends and fitting new Tundish or is there a procedure with shutting of valves etc. would...

I have recently installed a new 300l vented thermal store, swapping out the standard 160l vented cylinder. Existing 4 gallon F & E tank in the loft was also with a new 25 gallon tank. The install pretty much used all the existing piping but I am not sure about the re-use of the existing vent...

I'm new to the form, so Hi everyone.
Can somebody explain why, with a modern boiler in an open-vent system, both the feed and vent are necessary. Surely the feed would cope with any expansion.
