numeric distributed matrix
integer indicating the number of decimal places
(round()) or significant digits (signif()) to be used.
Negative values are allowed (see 'Details').
Returns a distributed matrix.
Rounding to a negative number of digits means rounding to a power of ten, so
for example round(x, digits = -2) rounds to the nearest hundred.
