## 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.
