Matematyka i statystyka
Descriptive statistics, percentiles, correlation, combinations, permutations, factorials and prime factorisation.
Kalkulator statystykiMean, median, mode, range, variance, standard deviation, standard error, quartiles and IQR from a list of numbers.Kalkulator percentylaCompute any percentile of a data set with linear interpolation, plus all deciles.Kalkulator korelacjiPearson and Spearman correlation, r², and the least-squares regression line for paired data.Kalkulator kombinacjiC(n,r) with exact BigInt arithmetic and a list of the actual combinations for small inputs.Kalkulator permutacjiP(n,r) ordered arrangements computed exactly with BigInt — no floating point rounding.Kalkulator liczb pierwszych FactorizationBreak any integer into prime factors and list every divisor with the divisor count.Weryfikator liczb pierwszych liczbyTest whether a number is prime and, if not, show its smallest divisors and divisor count.Primes Up To NList every prime number up to a limit, with the count.Kalkulator Math odległościEvaluate arithmetic expressions with correct precedence, powers, factorials, functions and constants.Kalkulator ułamekSimplify fractions, convert decimals to exact fractions and add, subtract, multiply or divide them.procentu to ułamekConvert any decimal to its exact simplest fraction using continued-fraction search with a tolerance.Add and Subtract FractionsAdd, subtract, multiply or divide fractions with the common denominator and GCD reduction shown.Drop bytesCuts 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 4.75Rotate leftRotates 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.Rotate rightRotates 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.Standard DeviationComputes 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 4.089281382128433Take bytesTakes a slice of the specified number of bytes from the data. Negative values are allowed.
