I really did not understand how the type assignment system works for variables in typescript. Can anyone help me why this does not work. Thank you
valorParcela:number;
totalCost:number;
VendaProdutoVendaNParcelas: number;
this.valorParcela = Number( this.totalCost / this.VendaProdutoVendaNParcelas).toFixed(2);
I expected a simple parseFloat
toFixed returns a string which you are assigning to a variable which should be number. You need another pair of () to convert the result of toFixed back to number
this.valorParcela = Number(( this.totalCost / this.VendaProdutoVendaNParcelas).toFixed(2));
Or you can use the unary + trick to perform number conversion:
this.valorParcela = +(this.totalCost / this.VendaProdutoVendaNParcelas).toFixed(2);
