this statement :
"The expression T(v) converts the value v to the type T."
is already correct as it is in my view.
What I found confusing is the code example, which doesn't appear to relate to this concept at all.
package main
import (
"fmt"
"math"
)
func main() {
var x, y int = 3, 4
var f float64 = math.Sqrt(float64(x*x + y*y))
var z uint = uint(f)
fmt.Println(x, y, z)
}
Instead, I would suggest a much more trivial code alternative demonstrates the effect more clearly by converting from float64 to int (and the loss of precision that causes)
package main
import (
"fmt"
)
func main() {
var x1, x2 float64 = 1.123, 2.345
var y1, y2 int = int(x1), int(x2) // Key Concept
fmt.Println(x1, x2)
fmt.Println(y1, y2)
}
// returns:
// 1.123 2.345
// 1 2
