We study the loss of significant βits (?base β digits) in floating point addition or subtraction. To do this, we calculate the conditional probability of a post-arithmetic normalization shift of m βits, given an exponent difference of k βits. The study is done for various bases β, under two different assumptions that the operands are selected at random from the logarithmic distribution or from the uniform distribution.
