You can write as many zeros as you want after 12358470000.0, it's still the same number as 12358470000
what is the problem with the following solution bro !
Check,it's the same as round(x,2).
y = round(x,-4);
add more test suites. You can simply write y=12358470000 to pass the test suites now. So add variations
The problem needs correction. Rounding to nearest 10,000 means no body cares about .000 values. y_correct = 12358470000.000; should be y_correct = 12358470000.
function y = round_ten_thou(x)
y = round(x/1e4)*1e4;
Make the vector [1 2 3 4 5 6 7 8 9 10]
