The calculator is solving an equation or program for its root. This might take a while.

Attempted to calculate the square root of a negative number.Statistics error:„Attempted to do a statistics calculation with n = 0.„Attempted to calculate sx sy, xˆ , yˆ , m, r, or b with n = 1.

„Attempted to calculate r, xˆ or xw with x–data only (all y–values equal to zero).

„Attempted to calculate xˆ , yˆ , r, m, or b with all x–values equal.

The magnitude of the number is too large to be converted to HEX, OCT, or BIN base; the number must be in the range

A running program attempted an eighth nested % label. (Up to seven subroutines can be nested.) Since SOLVE and ≥ FN each uses a level, they can also generate this error.

The condition checked by a test instruction is true. (Occurs only when executed from the keyboard.)
