When an error occurs, its code is assigned to variable errCode. User-defined programs and functions can examine errCode to determine the cause of an error. For an example of using errCode, See Example 2 under the Try command, here.
Note: Some error conditions apply only to TI‑Nspire™ CAS products, and some apply only to TI‑Nspire™ products.
Error code |
Description |
||||||||||||
10 |
A function did not return a value |
||||||||||||
20 |
A test did not resolve to TRUE or FALSE. Generally, undefined variables cannot be compared. For example, the test If a<b will cause this error if either a or b is undefined when the If statement is executed. |
||||||||||||
30 |
Argument cannot be a folder name. |
||||||||||||
40 |
Argument error |
||||||||||||
50 |
Argument mismatch Two or more arguments must be of the same type. |
||||||||||||
60 |
Argument must be a Boolean expression or integer |
||||||||||||
70 |
Argument must be a decimal number |
||||||||||||
90 |
Argument must be a list |
||||||||||||
100 |
Argument must be a matrix |
||||||||||||
130 |
Argument must be a string |
||||||||||||
140 |

165 |
Batteries too low for sending or receiving Install new batteries before sending or receiving. |

170 |
Bound The lower bound must be less than the upper bound to define the search interval. |
||||||||||||
180 |
Break The d or c key was pressed during a long calculation or during program execution. |
||||||||||||
190 |
Circular definition This message is displayed to avoid running out of memory during infinite replacement of variable values during simplification. For example, a+1->a, where a is an undefined variable, will cause this error. |
||||||||||||
200 |
Constraint expression invalid For example, solve(3x^2-4=0,x) | x<0 or x>5 would produce this error message because the constraint is separated by “or” instead of “and.” |
||||||||||||
210 |
Invalid Data type An argument is of the wrong data type. |
||||||||||||
220 |
Dependent limit |
||||||||||||
230 |
Dimension A list or matrix index is not valid. For example, if the list {1,2,3,4} is stored in L1, then L1[5] is a dimension error because L1 only contains four elements. |
||||||||||||
235 |
Dimension Error. Not enough elements in the lists. |
||||||||||||
240 |
Dimension mismatch Two or more arguments must be of the same dimension. For example, [1,2]+[1,2,3] is a dimension mismatch because the matrices contain a different number of elements. |
||||||||||||
250 |
Divide by zero |
||||||||||||
260 |
Domain error An argument must be in a specified domain. For example, rand(0) is not valid. |

The first argument of nSolve must be an equation in a single variable. It cannot contain a non-valued variable other than the variable of interest. |
||||||||||||
320 |
First argument of solve or cSolve must be an equation or inequality For example, solve(3x^2-4,x) is invalid because the first argument is not an equation. |
||||||||||||
345 |

350 |
