Enter commands in the bottom text field of the applet window. To exit the calculator, just close the applet window or enter commands exit or quit.
The calculator commands are: clear, Clear, clean, Clean, dup, pop, size, swap, save, milk, factorial, font, tic, toc, Euclid, cubeRoot, sqrt, +, -, *, /, ++, --, %, **, ^, &, |, ~, <<, >>, =, ==, !=, <, <=, >, >=, who, ;, !!, !<num>, history, repeat ... until, if ... [else ...] end, while ... end, run, echo, #, exit, quit, rand, prime, BigInteger, ECadd, ECmul, ECmul2, IDEAadd, IDEAaddInverse, IDEAmul, IDEAmulInverse; plus all of the methods from the BigInteger class by name: abs, add, and, andNot, bitCount, bitLength, byteValue, byteValueExact, clearBit, compareTo, divide, divideAndRemainder, doubleValue, equals, flipBit, floatValue, gcd, getLowestSetBit, hashCode, intValue, intValueExact, isProbablePrime, longValue, longValueExact, max, min, mod, modInverse, modPow, multiply, negate, nextProbablePrime, not, or, pow, probablePrime, remainder, setBit, shiftLeft, shiftRight, shortValue, shortValueExact, signum, subtract, testBit, toByteArray, toString, valueOf, xor.
Notes
probablePrime uses an implicit certainty value of 100 so, for example, 1024 probablePrime is the same as 1024 100 prime
toString and BigInteger support bases 2 to 36, 64, and 256 (ASCII, with C escape sequences, blank = \_).
