Determines the fewest bits necessary to express the BigInt
,
not including the sign.
Converts this BigInt
into a BigUint
, if it’s not negative.
Returns (self ^ exponent) mod modulus
Note that this rounds like mod_floor
, not like the %
operator,
which makes a difference when given a negative self
or modulus
.
The result will be in the interval [0, modulus)
for modulus > 0
,
or in the interval (modulus, 0]
for modulus < 0
Panics if the exponent is negative or the modulus is zero.
Returns the truncated principal square root of self
–
see Roots::sqrt.
Returns the truncated principal cube root of self
–
see Roots::cbrt.
Returns the truncated principal n
th root of self
–
See Roots::nth_root.
Returns the number of least-significant bits that are zero,
or None
if the entire number is zero.
Returns whether the bit in position bit
is set,
using the two’s complement for negative numbers
Sets or clears the bit in the given position, using the two’s complement for negative numbers
Note that setting/clearing a bit (for positive/negative numbers, respectively) greater than the current bit length, a reallocation may be needed to store the new digits
