round_bankers

description

Syntax

round_bankers(x), round_bankers(x, d) Rounds the argument x to d specified decimal places. d defaults to 0 if not specified. If d is negative, the left d digits of the decimal point are 0. If x or d is null, null is returned.

  • If the rounding number is halfway between two numbers, the function uses banker’s rounding.
  • In other cases, the function rounds numbers to the nearest integer.
