RPN Calculator

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A shared, stack-based Reverse Polish Notation calculator realm. Anyone can push tokens onto a single shared stack: integers are pushed as-is, while an operator (+, -, *, /) pops the top two operands and pushes the result. Divide-by-zero and stack underflow abort the transaction, and Clear resets the stack. Render shows the current stack (bottom→top), the top value as the result, and a usage guide.

Realm path

Example calls

# Compute (5 3 +) = 8
Push("5")
Push("3")
Push("+")

# Chain: (10 4 -) 2 * = 12
Push("10")
Push("4")
Push("-")
Push("2")
Push("*")

# Reset
Clear()
