Math.Tests.Exponentiation

Tests the Exponentiation block with multiple exponent values.

Mirrors the MSL Exponentiation test structure: a ramp from -2 to 2 feeds blocks with even (2), odd (3), unit (1), and zero (0) exponents. The zero-exponent case uses a Max block to ensure positive input for the inverse exponent test.
