Synonyms
1. Flow, gush, spout, spurt refer to certain of the movements characteristic of fluids. Flow is the general term: Water flows. A stream of blood flows. To gush is to rush forth copiously from a cavity, in as large a volume as can issue therefrom, as the result of some strong impelling force: The water will gush out if the main breaks. Spout and spurt both imply the ejecting of a liquid from a cavity by some internal impetus given to it. Spout implies a rather steady, possibly well-defined, jet or stream, not necessarily of long duration but always of considerable force: A whale spouts. Spurt implies a forcible, possibly sudden, spasmodic, or intermittent issue or jet: The liquid spurted out suddenly when the bottle cap was pushed in. Spout applies only to liquids; the other terms apply also to gases. 7. run. 9. teem.

Old English flowan "to flow, stream, issue; become liquid, melt; abound, overflow" (class VII strong verb; past tense fleow, past participle flowen), from Proto-Germanic *flo- (cf. Middle Dutch vloyen, Dutch vloeien "to flow," Old Norse floa "to deluge," Old High German flouwen "to rinse, wash"), probably from PIE *pleu- "flow, float" (see pluvial). The weak form predominated from 14c., but strong past participle flown is occasionally attested through 18c. Related: Flowed; flowing.

underflow in Technology
programming
(or "floating point underflow", "floating underflow", after "overflow") A condition that can occur when the result of a floating-point operation would be smaller in magnitude (closer to zero, either positive or negative) than the smallest quantity representable. Underflow is actually (negative) overflow of the exponent of the floating point quantity. For example, an eight-bit twos complement exponent can represent multipliers of 2^-128 to 2^127. A result less than 2^-128 would cause underflow.
Depending on the processor, the programming language and the run-time system, underflow may set a status bit, raise an exception or generate a hardware interrupt or some combination of these effects. Alternatively, it may just be ignored and zero substituted for the unrepresentable value, though this might lead to a later divide by zero error which cannot be so easily ignored.
