round_bankers

description

Syntax

T round_bankers(T 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.
