Implementation edit is for fixing errors and enhancing with metadata.

Instead of changing the code of the snippet, consider creating another Clojure implementation.

Other implementations

import "strconv"

f, err := strconv.ParseFloat(s, 64)

f = s.to_f

import locale

s = u'545,2222'
locale.setlocale(locale.LC_ALL, 'de')
f = locale.atof(s)

f = float(s)

sysutils

f := StrToFloat(s);

let f = s.parse::<f32>().unwrap();

read s :: Double

import std.conv;

float f = s.to!float;

f = num.parse(s);

uses sysutils;

f := s.ToExtended;

$f = floatval($s);

let f = +s

f = float(s)

String floatString = "14.5";
float x = Float.parseFloat(floatString);
double y = Double.parseFloat(floatString);

my $f = $s;

read(s,'(g0)')f

read (unit=s,fmt=*) f

var f=float.Parse(s);

float f = std::stof(s);

(Float/parseFloat s)

let f: f32 = s.parse().unwrap();
