Warning Codes and Messages
You can use the warnCodes() function to store the codes of warnings generated by
evaluating an expression. This table lists each numeric warning code and its associated
message. For an example of storing warning codes, see warnCodes(), page 165.
Warning
code Message
10000 Operation mightintroduce false solutions.
10001 Differentiating an equation may produce a false equation.
10002 Questionable solution
10003 Questionable accuracy
10004 Operation mightlose solutions.
10005 cSolve mightspecify more zeros.
10006 Solve may specify more zeros.
10007 More solutions may exist. Try specifying appropriate lower andupper bounds and/or a
guess.
Examples using solve():
• solve(Equation, Var=Guess)|lowBound<Var<upBound
• solve(Equation, Var)|lowBound<Var<upBound
• solve(Equation, Var=Guess)
10008 Domain of the result might be smaller than the domain of the input.
10009 Domain of the result might be larger than the domain of the input.
10012 Non-real calculation
10013
∞^0 or undef^0 replaced by 1
10014 undef^0 replaced by 1
10015
1^∞ or 1^undef replaced by 1
10016 1^undef replaced by 1

10018 Operation requires and returns 64 bit value.
10019 Resource exhaustion, simplification mightbe incomplete.
10020 Trig function argumenttoo big for accurate reduction.
10021 Input contains an undefinedparameter.
