OVERFLOW / ERROR CONDITIONS

A symbol “ E ” is indicated on the display when any of the following conditions occur and further calculation becomes impossible. Just press [ ON/C ] to release those overflow or error indicator and the subsequent calculation can then be performed.

•An intermediate or final calculation result exceed 1 x 10 100 (including memory calculations).

•You try to divide by zero.

•The number of low priority storage levels exceeds 6 in a parentheses calculation or nesting parentheses exceed 7 in one level. (Even if the number of levels is within 6, an error might occur

if you are using memories Ka or Kb, or program memories.)
