truncate

Truncate is the removal or truncation of least significant numbers in long columns of numbers, without regard to rounding up or down. It is concerned solely with reducing the length of the word, since truncation simply eliminates the superfluous numbers.

Truncate can be applied to numbers or bits with the highest significance, Most Significant Bit (MSB), as well as to the least significant numbers, Least Significant Bit (LSB), and is used to reduce computation time.

Truncation is applied when certain components or programs can only process a certain word length, but more comprehensive word lengths are available from A/D converters or from previous computing operations. For example, if the word length after an arithmetic operation is 32 bits and the downstream components can only process 24 bits, then the superfluous eight bits are simply truncated.
