result = DoubleExtensions.RoundOff(d, decimals, mode)

Rounds using arithmetic (5 rounds up) symmetrical (up is away from zero) rounding

d

A double number to be rounded.

decimals

mode

The midpoint rounding mode

Returns: The number nearest d with precision equal to decimals. If d is halfway between two numbers, then the nearest whole number away from zero is returned.
