Performs division on felt252 values in Cairo’s finite field. Unlike regular integer division, felt252 division returns a field element n that satisfies the equation: n * rhs ≡ lhs (mod P), where P is the felt252 prime.

Examples

use core::felt252_div;

// Division with 0 remainder works the same way as integer division.
assert!(felt252_div(4, 2) == 2);

// Division with non 0 remainder returns a field element n where n * 3 ≡ 4 (mod P)
assert!(felt252_div(4, 3) ==
