ERROR TYPE Possible Causes and Suggested Remedies
MEMORY Memory is insufficient to perform the instruction or
function. You must delete items from memory before
executing the instruction or function.
Recursive problems return this error; for example, graphing
the equation Y1=Y1.
Branching out of an If/Then, For(, While, or Repeat loop
with a Goto also can return this error because the End
statement that terminates the loop is never reached.
Attempting to create a matrix with larger than 400 cells.
MemoryFull
You are unable to transmit an item because the receiving
unit’s available memory is insufficient. You may skip the
item or exit receive mode.
During a memory backup, the receiving unit’s available
memory is insufficient to receive all items in the sending
unit’s memory. A message indicates the number of bytes
the sending unit must delete to do the memory backup.
Delete items and try again.
MODE You attempted to store to a window variable in another
graphing mode or to perform an instruction while in the
wrong mode; for example, DrawInv in a graphing mode
other than Func.
NO SIGN
CHANGE
The solve( function or the equation solver did not detect a
sign change.
You attempted to compute æ when FV, (Ú PMT), and PV
are all 0, or when FV, (Ú PMT), and PV are all _ 0.
You attempted to compute irr( when neither CFList nor
CFO is >0, or when neither CFList nor CFO is <0.
NONREAL
ANSWERS
In Real mode, the result of a calculation yielded a complex
result. . The TI-84PlusCE allows for undefined values on a
graph.
OVERFLOW You attempted to enter, or you have calculated, a number
that is beyond the range of the graphing calculator. The
TI-84PlusCE allows for undefined values on a graph.
RESERVED You attempted to use a system variable inappropriately.
SINGULAR
MATRIX
A singular matrix (determinant = 0) is not valid as the
argument for L1.
The SinReg instruction or a polynomial regression
generated a singular matrix (determinant=0) because the
algorithm could not find a solution, or a solution does not
exist.
The TI-84PlusCE allows for undefined values on a graph.
