// Converting and parsing between numbers and text. A conversion can't fail; a
// parse can, so it hands its failure back as an Option you match — never a crash.

// Conversions between numbers, and rendering a number as text, always work.
var price = 3.99
let whole = int(price)        // 3 — drops the fraction
let asFloat = float(whole)    // 3.0 — widens back
let label = string(price)     // "3.99"
print("whole:", whole, "asFloat:", asFloat, "label:", label)

// Reading a number out of text is the fallible one. parseInt answers with an
// Option: some(n) when the text was a number, none when it was not.
match parseInt("42") {
    some(let n) => print("parsed an int:", n)
    none        => print("not an int")
}

match parseInt("oops") {
    some(let n) => print("unexpected:", n)
    none        => print("\"oops\" is not a number — no crash, just none")
}

// parseFloat is the same shape for fractions.
match parseFloat("3.14") {
    some(let f) => print("parsed a float:", f)
    none        => print("not a float")
}
