Description
Prefix approximate with ≈ and a space, otherwise equals and a space.
Numeric-looking text has both a value and a written form. Signs, decimal places, exponent markers and trailing zeros can carry display information that ordinary numeric conversion discards; formatting a token does not verify its meaning.
Prefix approximate with ≈ and a space, otherwise equals and a space.
When to use this tool
Use Numeric Approximation Symbol Prefix when you need the specified literal representation or text-level numeric diagnostic.
How to use the tool and how it works
- Enter token, approximate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read text. Use the output convention below.
Require nonempty token. Prefix approximate with ≈ and a space, otherwise equals and a space.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Token | Required. Text; maximum UTF-16 length 8192. |
| approximate | Approximate | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| text | Literal formatted output under the stated grammar and display convention. | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"token": "3.14",
"approximate": true
},
"output": {
"text": "≈ 3.14"
}
}Limitations and assumptions
- The tool does not establish approximation error or actual equality; both the token and assertion are caller supplied.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use a locale-aware or destination-specific formatter when broader parsing and presentation rules are needed. Retain original text when lexical precision matters and validate numeric meaning separately.
