It returns `cbrt(x)`

. It gets more accurate as `iter`

gets bigger.

a = v1 / v3, b = v2 / v3 where the return value is `(v1, v2, v3)`

It returns `cos(x)`

. It gets more accurate as `iter`

gets bigger.

f(a) = v1, f(b) = v2, f’(a) = v3, f’(b) = v4

It ignores `v2`

and `v4`

if `a == b`

.

pre-calculated value of e. It’s equal to `e_iter(15)`

.

It returns an approximate value of E.
It gets more and more accurate as `k`

gets bigger.

It returns `e^x`

. It gets more accurate as `iter`

gets bigger.

`p`

: `Vec<(x, y)>`

where `f(x) = y`

`p`

: `Vec<(x, y)>`

where `f(x) = y`

You may find this function useful when you’re dealing with

ieee 754 numbers.

This function returns

`(neg, exp, frac)`

, which means

`n`

is

`(-1)^(neg) * 2^(exp) * (1 + frac/2^23)`

regardless of denormalization.

It returns (false, i32::MIN, 0) when n is 0.

This function returns

`(neg, exp, frac)`

, which means

`n`

is

`(-1)^(neg) * 2^(exp) * (1 + frac/2^52)`

regardless of denormalization.

It returns (false, i32::MIN, 0) when n is 0.

f(a) = v1, f(b) = v2

If `a == b`

, it returns a const function.

pre-calculated value of ln2. It’s equal to `ln2_iter(11)`

.

It returns an approximate value of ln(2).
It gets more and more accurate as `k`

gets bigger.
For now, `k`

should be less than 200.

It returns `ln(x)`

. It gets more accurate as `iter`

gets bigger. It panics when `x`

is less than 0.

It returns log(x) with base `base`

. It gets more accurate as `iter`

gets bigger. It panics when `x`

or `base`

is less than or equal 0.

pre-calculated value of pi. It’s equal to `pi_iter(7)`

.

It returns an approximate value of PI.
It gets more and more accurate as `k`

gets bigger.
For now, `k`

should be less than 255.

It returns `a^b`

. It gets more accurate as `iter`

gets bigger. If `b`

is an integer, try `Ratio::pow_i32`

instead. It panics when `a`

is less than 0. `0^0`

is 0.

f(a) = v1, f(b) = v2, f(c) = v3

If the input has inconsistent values (eg. f(3) = 4, f(3) = 5), it ignores an arbitrary one.

It returns `sin(x)`

. It gets more accurate as `iter`

gets bigger.

It returns `sqrt(abs(x))`

. It gets more accurate as `iter`

gets bigger.

It returns `tan(x)`

. It gets more accurate as `iter`

gets bigger.
