bigint
Absolute value. abs(a)==a if a>=0. abs(a)==-a if a<0
+number
Returns the bitlength of a number
+egcdReturn
An iterative implementation of the extended euclidean algorithm or extended greatest common divisor algorithm. +Take positive integers a, b as input, and return a triple (g, x, y), such that ax + by = g = gcd(a, b).
+bigint
Greatest-common divisor of two integers based on the iterative binary algorithm.
+bigint
The least common multiple computed as abs(a*b)/gcd(a,b)
+bigint
Maximum. max(a,b)==a if a>=b. max(a,b)==b if a<=b
+bigint
Minimum. min(a,b)==b if a>=b. min(a,b)==a if a<=b
+bigint
| NaN
Modular inverse.
+bigint
Modular exponentiation b**e mod n. Currently using the right-to-left binary method
+bigint
Finds the smallest positive element that is congruent to a in modulo n
+Promise.<boolean>
The test first tries if any of the first 250 small primes are a factor of the input number and then passes several +iterations of Miller-Rabin Probabilistic Primality Test (FIPS 186-4 C.3.1)
+Promise.<bigint>
A probably-prime (Miller-Rabin), cryptographically-secure, random-number generator. +The browser version uses web workers to parallelise prime look up. Therefore, it does not lock the UI +main process, and it can be much faster (if several cores or cpu are available). +The node version can also use worker_threads if they are available (enabled by default with Node 11 and +and can be enabled at runtime executing node --experimental-worker with node >=10.5.0).
+bigint
A probably-prime (Miller-Rabin), cryptographically-secure, random-number generator. +The sync version is NOT RECOMMENDED since it won't use workers and thus it'll be slower and may freeze thw window in browser's javascript. Please consider using prime() instead.
+bigint
Returns a cryptographically secure random integer between [min,max]. Both numbers must be >=0
+Promise.<(Buffer|Uint8Array)>
Secure random bits for both node and browsers. Node version uses crypto.randomFill() and browser one self.crypto.getRandomValues()
