Infinite Result
HP HP Calculator
Severity: MinorWhat Does This Error Mean?
Infinite Result means a calculation produced infinity — usually from dividing by zero or evaluating a function at a singularity. Check your denominator or function input.
Affected Models
- HP Prime
- HP 50g
- HP 48GX
Common Causes
- Division by zero
- Tangent of 90° (or π/2 radians)
- Logarithm approaching zero
- Function evaluated at a singularity
How to Fix It
-
Check for division by zero in your expression.
Any expression with /0 produces infinity.
-
Check if you are evaluating a function at a known singularity.
tan(90°) = infinity. 1/0 = infinity. Adjust your input value slightly to avoid the singularity.
-
For limits: use the CAS to evaluate properly.
On HP Prime: use the limit() function in CAS mode. This handles singularities mathematically.
Frequently Asked Questions
Is infinity a number?
Mathematically, infinity is a concept, not a number. Calculators report it as an error because they cannot represent an infinite value.
Can the HP Prime work with infinity?
In CAS mode, the HP Prime can handle symbolic infinity in limits and calculus. In Home mode, it reports an error.
