Signed bigint values.

Generate any bigint value taken into the specified range. Both lower bound and upper bound are included into the range of possible values.

fc.bigInt()
fc.bigInt({min?, max?})
fc.bigInt(min, max)

with:

min? — lower bound of the range (included)
max? — upper bound of the range (included)

Usages:

fc.bigInt();
