Returns the rounded value of a numeric expression.
ROUND ( num_expression [, rounding_factor ] ) ;
Example This example illustrates four calls to the ROUND function:
-- rounding_factor 2 returns 2953861.83
ROUND ( 2953861.8320, 2 )
-- rounding_factor -2 returns 2953900.00
ROUND ( 2953861.8320, -2 )
-- rounding_factor 0 returns 2953862.00
ROUND ( 2953861.8320, 0 )
-- No rounding_factor argument also returns 2953862.00
ROUND ( 2953861.8320 )
In each case the num_expression is 2953861.8320. In the first call the rounding_factor is 2,
in the second call the rounding_factor is -2, in the third call the rounding_factor is 0, and in
the fourth call no rounding_factor is specified.
