Abstract
A method and apparatus for determining a data storage bit width and a method for storing exponential data. The method for determining the data storage bit width includes: acquiring data to be stored, the number of which is at least 4; dividing the data into blocks according to a preset number 2, n is an integer greater than or equal to 2; determining effective bit numbers and a value of a maximum effective bit number in a block; dividing data in the block equally into a first sub-block and a second sub-block, acquiring effective bit numbers in first and second sub-blocks; performing a differential calculation on effective bit numbers in first and second sub-blocks to obtain an effective differential value; determining a storage bit width for storing effective differential value according to a preset storage bit width interval to which the value of maximum effective bit number belongs.
