Quick Answer
The answer is `tonumber()` and `int()`. Both of these eval functions are designed to convert a string representation of a number into an actual numeric value, though they handle the conversion slightly differently: `tonumber()` can convert a string to either an integer or a floating-point number, making it the more flexible option, while `int()` specifically converts a string to an integer, truncating any decimal portion. On the Splunk Core Certified Power User SPLK-1003 exam, this question tests your understanding of how Splunk’s eval command handles data type conversion, a common task when cleaning or preparing field values for calculations. A frequent trap is assuming only `tonumber()` works for this purpose, but `int()` is equally valid for integer strings. To remember: think of `int()` as the integer-only converter and `tonumber()` as the general-purpose converter—both turn text into math-ready numbers.
This SPLK-1003 practice question tests your understanding of advanced searching and statistics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following eval functions can be used to convert a string to a numeric value?
tostring()
Why wrong: `tostring()` converts to string.
number()
Why wrong: `number()` is not a valid eval function.
int()
`int()` converts a value to an integer, working on strings as well.
str()
Why wrong: `str()` converts to string, opposite of what's needed.
tonumber()
`tonumber()` explicitly converts a string to a number.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
int()
The `int()` function (option C) converts a string representation of an integer into a numeric integer value, and `tonumber()` (option E) converts a string to a floating-point or integer number, making both valid for converting strings to numeric values in Splunk's eval command.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
tostring()
Why it's wrong here
`tostring()` converts to string.
number()
Why it's wrong here
`number()` is not a valid eval function.
int()
Why this is correct
`int()` converts a value to an integer, working on strings as well.

tonumber()
Why this is correct

Common exam traps
Splunk often tests candidates' familiarity with Splunk's specific eval function names, and the trap here is that `number()` and `str()` sound plausible but are not valid Splunk functions, leading candidates to select them based on general programming knowledge rather than Splunk's actual syntax.
Detailed technical explanation
Under the hood, `tonumber()` can handle strings with leading/trailing whitespace and returns `NULL` for non-numeric strings, while `int()` truncates decimal values to integers. In real-world scenarios, these functions are essential for cleaning log data where fields like `status_code` are stored as strings, enabling arithmetic operations or comparisons in search queries.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SPLK-1003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
