import "joelpurra/jq-bigint" as BigInt;

# BigInt::negate:                # . * -1
# BigInt::lessOrEqual(x; y):     # x <= y
# BigInt::long_add(x;y):         # x+y
# BigInt::long_minus(x;y):       # x-y
# BigInt::long_power(i):         # .^i
# BigInt::long_multiply(x;y):    # x*y
# BigInt::long_divide(x;y):      # x/y => [q,r]
# BigInt::long_div(x;y):         # integer division
# BigInt::long_mod(x;y):         # %

# In all cases, x and y must be strings; . and i should be an integer or a string.
