Descriptive statistics, percentiles, correlation, combinations, permutations, factorials and prime factorisation.
통계 계산기Mean, median, mode, range, variance, standard deviation, standard error, quartiles and IQR from a list of numbers.백분위 계산기Compute any percentile of a data set with linear interpolation, plus all deciles.상관 계산기Pearson and Spearman correlation, r², and the least-squares regression line for paired data.조합 계산기C(n,r) with exact BigInt arithmetic and a list of the actual combinations for small inputs.순열 계산기P(n,r) ordered arrangements computed exactly with BigInt — no floating point rounding.소수 Factorization 계산기Break any integer into prime factors and list every divisor with the divisor count.소수 숫자 검사기Test 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.Math 수식 계산기Evaluate arithmetic expressions with correct precedence, powers, factorials, functions and constants.분수 계산기Simplify fractions, convert decimals to exact fractions and add, subtract, multiply or divide them.10 진 to 분수Convert 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.
