How do I get from var x:number = 1200 to x = 1.200 or var x: number = 8 to x = 8.0 ?

Method toFixed will help you.

x = 1200
x = x.toFixed(1) // 1200.0

actually, don't know what you want :

const conv = (num) => {
  arr = [...(''   num)] ;
  arr.splice(1, 0, '.')
  if (arr[arr.length-1] == '.') arr.push('0') ;
  return arr.join('')
}
console.log( conv(1200), conv(8) ) // 1.200 8.0
