Usage

Deficient(n, Rmpfr = TRUE, PrecisionBits = 496)

Arguments

n

the number of first n entries from the sequence.

Rmpfr

a logical; TRUE to use large number representation, FALSE otherwise.

PrecisionBits

a positive integer for precision bits larger than 2.

Value

a vector of length n containing first entries from the sequence.

# NOT RUN {
## generate first 30 Deficient numbers
first30 = Deficient(30)

## print without trailing 0's.
print(first30, drop0trailing = TRUE)

# }
