Trait UncheckedSqrt 

pub trait UncheckedSqrt {
    // Required method
    fn unchecked_sqrt(self) -> Self;
}

Returns the square root of self without checking the input.

Panics

Panics if self is negative.

Required Methods

fn unchecked_sqrt(self) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl UncheckedSqrt for Dec19x19

Tests

check! ( [Dec19x19::unchecked_sqrt, Dec19x19::checked_sqrt] {
    (Dec19x19!(0)) => Dec19x19!(0),
    (Dec19x19::MAX) => Dec19x19!(4_124_817_371.235_594_858_790_322_117_5),
    (-Dec19x19::SMALLEST_STEP) => FAIL,
});
// Precision test.
assert_eq!(Dec19x19!(1e-18).unchecked_sqrt() * Dec19x19!(1e-18).unchecked_sqrt(), Dec19x19!(1e-18));

Validation

fuzzy1::<Dec19x19, BigDecimal>(Series::new(0..=19, 0..=19),
    |f1, b1| should_eq(f1.abs().unchecked_sqrt(), b1.abs().sqrt().unwrap())
);
