strconv is Go's standard-library package for converting strings to and from basic numeric and quoted representations.
- How it is used
- Supports string conversion in custom formatting code and HTTP handlers that receive numeric values as form strings.
- How deep it goes
- Demonstrates Itoa and Atoi inside working implementations, including dynamic formatting and conversion-error handling.
- Examples
- Uses currency amounts such as 10.50 and habit-frequency form fields as concrete conversion examples.
- What you can do after
- Apply it via Itoa and Atoi to construct numeric formats and parse integer-valued HTTP form inputs.

Go in Action, Second Edition
strconv is a Go standard-library package for converting between strings and basic data types such as integers, floating-point numbers, and booleans.
- How it is used
- Converts textual CLI, file, environment, and configuration values into typed data and formats results for output.
- How deep it goes
- Explains parsing, validation, error handling, and formatting controls, but does not descend into conversion internals.
- Examples
- Uses port parsing with range validation, Boolean debug flags, and type-switched formatting for configuration display.
- What you can do after
- Apply strconv to parse validated configuration values and generate controlled string representations for logs, displays, and output.
