Answer 2

Divya Mohan its rounding problem. Js store Number in floating point, check the article i linked

Answer 3

Just check this
Var b = 9007199254740993
Console.log(b);

It still print 9007199254740992
I think it's a bug of sololearn with such a big number

Answer 4

Divya Mohan it's not a bug the maximum safe integer is 900719925470992 ,but logging out 900719925470992+2 works unlike +1

Answer 5

Are you taking about Math.pow() ??

Divya Mohan check the output for these two lines
console.log(x);
console.log(x+1);
