// This test is intended to check that the whole stdlib is present

// and the other with all of them.

// This tolerance is ~9000x the machine epsilon, which is quite lenient and should work across
// different platforms and math libraries.
//
// We use a combination of absolute and relative error to handle both small and large values:
// - For values near zero, we use absolute error to avoid division issues
// - For larger values, we use relative error to maintain precision
//
// This correctly handles cases like:
// assertClose(1e-15, 0) - should pass (both are essentially zero)
// assertClose(-100, 0) - should fail (significant difference)
// assertClose(std.sin(std.pi), 0) - should pass (tiny floating point error)
