With .toFixed(2) I always get 2 decimals, even if the number is 2.00
Can I get 2 instead?
Example:
function toFixedIfNecessary( value, dp ){
return +parseFloat(value).toFixed( dp );
}
console.log( toFixedIfNecessary( 1.999, 2 )); // 2
console.log( toFixedIfNecessary( 2, 2 )); // 2
console.log( toFixedIfNecessary( 2.1, 2 )); // 2.1
console.log( toFixedIfNecessary( 2.05, 2 )); // 2.05
console.log( toFixedIfNecessary( 2.05342, 2 )); // 2.05
console.log( toFixedIfNecessary( 2.04999, 2 )); // 2.05
console.log( toFixedIfNecessary( 2.04499, 2 )); // 2.04
console.log( toFixedIfNecessary( 2.053435, 2 )); // 2.05
console.log( toFixedIfNecessary( 2.057435, 2 )); // 2.06
