Error codes for particular operations.

Additional Information

Normally, if the result of an ALU operation is mathematically undefined (e.g. dividing by zero), the VM Reverts.
However, if the F_UNSAFEMATH flag is set, $err is set to true and execution continues.

Returns

• [u64] - A VM error code.

Examples

use std::{registers::error, flags::{disable_panic_on_unsafe_math, enable_panic_on_unsafe_math}};

fn foo() {
    disable_panic_on_unsafe_math();
    let bar = 1 / 0;
    assert(error() == 1);
    enable_panic_on_unsafe_math();
}
