Abstract
Embodiments of the present disclosure propose an Erasing-based Lossless Floating-point compression method, i.e., Elf. The main idea of Elf is to erase the last few bits (i.e., set them to zero) of floating-point values, so the XORed values are supposed to contain many trailing zeros, where the erased bits are determined based on the decimal place count and the digits on the exponent bits.
