hi ive created visual calc using html and its looks like this ..

| 1 | 2 | 3 | | 4 | 5 | 6 | | 7 | 8 | 9 | | | . | |

and ive created function called `number()`

on click on each html element
and this is it

number(number) { this.total_quantity_discount_price = this.total_quantity_discount_price+''+number; this.total_quantity_discount_price = parseFloat(this.total_quantity_discount_price); },

with numbers `0123456789`

everything is working fine but my problem with the `.`

how can i add `.`

Use `Number`

constructor like

this.total_quantity_discount_price = Number(this.total_quantity_discount_price+''+number);

let n=Number(4+'.'+5) // the n is a number which you could add it to another console.log(n) console.log(n+1) console.log(n-3)
