Idiom #79 Convert integer to floating point number

Declare the floating point number y and initialize it with the value of the integer x .

let y = float_of_int(x)

Y : constant Float := Float (X);

float y = (float)x;

(def y (float x))

float y = static_cast<float>(x);

float y = x;

import std.conv : to;

int x;
float y = to!float(x);
// or
float y = cast(float) x;

double y = x.toDouble();

y = x / 1

real :: y
y = x

y := float64(x)

y = fromInteger x :: Double

let y = x + .0

int x = 10
float y = (float)x;
System.out.println(y);

Float y = Float.parseFloat(String.valueOf(x));

float y = x;

import java.math.BigDecimal;

float y = new BigDecimal(x).floatValue();

(defparameter *y* (float x))

y = x + .0

y = (16 ^ 13) + x - (16 ^ 13)

$y = (float) $x;

var
  y: single;
begin
  y := x;
end;

my $y = $x;

y = float(x)

y = x.to_f

let y = x as f64;

Do you know the best way to do this in your language ? New implementation...
