Ivy is a calculator with APL syntax and functions developed by Rob Pike with the Go programming language (itself developed by Pike and others). Built-in functions are written with one or more ASCII characters, and use either the C-like symbols of Go or short names such as div or rot. It emphasizes high-precision computation, using exact rationals when possible and high-precision floating-point numbers otherwise.
Ivy allows user-defined functions (called operators), but not higher-order operators; it has only the four built-in operators Reduce, Scan, Outer Product, and Inner Product. Functions are defined with the op keyword, with a declaration that matches the way the function will be used followed by = and a body of one or more lines (the result of the last is returned). Among APLs, this syntax most closely resembles that of A+.
