second argument is -1 means rounding by 10..
so result will be from series 10,20,30...100,110,120....

here 123 is near to 120 and 127 is near to 130

SQL

SELECT ROUND(123.89, -1) [123 is near 120], ROUND(127.89, -1) [127 is near 130]
--means rounding by 10

same way if second argument is -2 means rounding by 100
so result will be from series 100,200,300...1000,1100,1200....

Happy Coding!

SELECT ROUND(123.89, -1)

Result:120.00

SELECT ROUND(123.89, 0)

Result:124.00

SELECT ROUND(123.89, 1)

Result:123.90

By this Example 2nd argument -1 is used to pointing the Position of Round of.
123.89 is near to 120
125 is 130
