ตัวตรวจสอบจำนวนเฉพาะตัวเลขTest whether a number is prime and, if not, show its smallest divisors and divisor count.PrimesUpToNList every prime number up to a limit, with the count.เครื่องคิด Math ระยะทางEvaluate arithmetic expressions with correct precedence, powers, factorials, functions and constants.เครื่องคิดเศษส่วนSimplify fractions, convert decimals to exact fractions and add, subtract, multiply or divide them.เปอร์เซ็นต์ to เศษส่วนConvert any decimal to its exact simplest fraction using continued-fraction search with a tolerance.AddandSubtractFractionsAdd, subtract, multiply or divide fractions with the common denominator and GCD reduction shown.DropbytesCuts a slice of the specified number of bytes out of the data. Negative values are allowed.MeanComputes the mean (average) of a number list. If an item in the string is not a number it is excluded from the list. e.g. 0x0a 8 .5 .5 becomes 4.75RotateleftRotates each byte to the left by the number of bits specified, optionally carrying the excess bits over to the next byte. Currently only supports 8-bit values.RotaterightRotates each byte to the right by the number of bits specified, optionally carrying the excess bits over to the next byte. Currently only supports 8-bit values.SleepSleep causes the recipe to wait for a specified number of milliseconds before continuing execution.StandardDeviationComputes the standard deviation of a number list. If an item in the string is not a number it is excluded from the list. e.g. 0x0a 8 .5 becomes 4.089281382128433TakebytesTakes a slice of the specified number of bytes from the data. Negative values are allowed.

Sources such as `cat -v`. Please be aware that when using `cat -v` ^_ (caret-underscore) will not be encoded, but represents a valid encoding (namely thFletcher-16 คำค้นThe Fletcher checksum is an algorithm for computing a position-dependent checksum devised by John Gould Fletcher at Lawrence Livermore Labs in the late 1970s.
