The strconv package provides functions to convert strings to integers, floats, and booleans, and vice versa.
The strconv package converts strings to and from basic data types like integers, floats, and booleans.
import "strconv"
// String to int
num, err := strconv.Atoi("42")
// Int to string
s := strconv.Itoa(100)
// String to float
f, err := strconv.ParseFloat("3.14", 64)
// String to bool
b, err := strconv.ParseBool("true")
The strconv package acts as a translator between text and numbers. You use it whenever you need to turn a user's typed input into a number for math, or turn a calculated number back into text for display. It's like a universal adapter that lets different data types talk to each other.
