Remove insignificant trailing zeros from a number?

Have I missed a standard API call that removes trailing insignificant zeros from a number?

var x = 1.234000; // to become 1.234
var y = 1.234001; // stays 1.234001

Number.toFixed() and Number.toPrecision() are not quite what I'm looking for.

Solution

  • If you convert it to a string it will not display any trailing zeros, which aren't stored in the variable in the first place since it was created as a Number, not a String.

    var n = 1.245000
var noZeroes = n.toString() // "1.245"
