Arbitrary Precision Rational Calculator

Display as:

This page performs arithmetic on rational numbers, “i / j” where “i” and “j” are arbitrarily large integers. All the arithmetic is exact. Literal integers are decimal unless obviously hex or prefixed by “0x”; fractional decimals work too. The operators are +, -, *, /, %, mod, and ^. The functions are sign, abs, floor, round, log10, gcd, inverse, random, and prime (hover for a description). Expressions can refer to other expressions by name. When you change an expression and press “tab”, all results that depend on the expression’s value are updated. Examples: Z_p, RSA, SOSP.
