## Changes
- Updated `DecimalFormatSymbols` to use period as decimal separator
(Locale.US)
- Fixed test expectations in `testComplexInputSchemaTool`:
- `formattedResult`: `"11,000"` → `"11.000"`
- `tags`: Added actual test values `["test", "calculator",
"integration"]`
- Fixed test expectations in `testComplexNestedSchema`:
- `formattedResult`: `"0,00"` → `"0.00"`
## Motivation
1. **Standard Decimal Notation**: Using a comma as a decimal separator
could be confusing as it's commonly used for thousands separators in
many locales. Standardizing on the period (`.`) follows international
conventions and makes the output clearer.
2. **Test Data Correction**: During the Validate PR workflow for #289,
discovered that the `tags` array in the `expectedContent` variable of
`testComplexInputSchemaTool()` was incorrectly set to an empty array,
which didn't match the actual input values being tested.
