In C# the following code returns 2:
double d = 2.9;
int i = (int)d;
Debug.WriteLine(i);
In Javascript, however, the only way of converting a "double" to an "int" that I'm aware of is by using Math.round/floor/toFixed etc. Is there a way of converting to an int in Javascript without rounding? I'm aware of the performance implications of Number() so I'd rather avoid converting it to a string if at all possible.
Use parseInt()
.
var num = 2.9
console.log(parseInt(num, 10)); // 2
You can also use |
.
var num = 2.9
console.log(num | 0); // 2
