// Package fr contains field arithmetic operations for modulus = 0x12ab65...000001.
//
// The API is similar to math/big (big.Int), but the operations are significantly faster (up to 20x for the modular multiplication on amd64, see also https://hackmd.io/@gnark/modular_multiplication)
//
// The modulus is hardcoded in all the operations.
//
// Field elements are represented as an array, and assumed to be in Montgomery form in all methods:
//
//	type Element [4]uint64
//
// # Usage
//
// Example API signature:
//
//	// Mul z = x * y (mod q)
//	func (z *Element) Mul(x, y *Element) *Element
//
// and can be used like so:
//
//	var a, b Element
//	a.SetUint64(2)
//	b.SetString("984896738")
//	a.Mul(a, b)
//	a.Sub(a, a)
//	 .Add(a, b)
//	 .Inv(a)
//	b.Exp(b, new(big.Int).SetUint64(42))
//
// Modulus q =
//
//	q[base10] = 8444461749428370424248824938781546531375899335154063827935233455917409239041
//	q[base16] = 0x12ab655e9a2ca55660b44d1e5c37b00159aa76fed00000010a11800000000001
