+This directory contains a corrected version of the paper with the following changes:
+ * All continuous constants for division by square-root were incorrect in the published version (mix-up)
+ * All binary32 values for two-input functions (multiplication, division, and division by square-root) were truncated instead of rounded
+ * In addition, the binary32 value for division with maximum norm was incorrect (a leading zero was missing in the underlying representation)
+
+ It also contains a .bib-entry for the paper.
+
+ It will contain continuous coefficients with higher precision than those given in the paper as well as improved continuous coefficients for functions involving square roots.
