Toán học & thống kê
Descriptive statistics, percentiles, correlation, combinations, permutations, factorials and prime factorisation.
Máy tính thống kêMean, median, mode, range, variance, standard deviation, standard error, quartiles and IQR from a list of numbers.Máy tính bách phân vịCompute any percentile of a data set with linear interpolation, plus all deciles.Máy tính tương quanPearson and Spearman correlation, r², and the least-squares regression line for paired data.Máy tính tổ hợpC(n,r) with exact BigInt arithmetic and a list of the actual combinations for small inputs.Máy tính hoán vịP(n,r) ordered arrangements computed exactly with BigInt — no floating point rounding.Máy tính số nguyên tố FactorizationBreak any integer into prime factors and list every divisor with the divisor count.Bộ kiểm tra số nguyên tố sốTest 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.Máy tính Math khoảng cáchEvaluate arithmetic expressions with correct precedence, powers, factorials, functions and constants.Máy tính phân sốSimplify fractions, convert decimals to exact fractions and add, subtract, multiply or divide them.phần trăm to phân sốConvert 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.
