ArrayTrait - Array Rounding functions

Required Methods

fn round(&self, decimals: &Array<isize>) -> Result<Array<N>, ArrayError>

Evenly round to the given number of decimals

Arguments

• decimals - Number of decimal places to round to (default: 0). If decimals is negative, it specifies the number of positions to the left of the decimal point

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, 8.0010, 22.234]);
assert_eq!(Array::flat(vec![2., 4.6, 8.001, 20.]), arr.round(&Array::flat(vec![0, 1, 3, -1]).unwrap()));

fn around(&self, decimals: &Array<isize>) -> Result<Array<N>, ArrayError>

Evenly round to the given number of decimals. alias on round

Arguments

• decimals - Number of decimal places to round to (default: 0). If decimals is negative, it specifies the number of positions to the left of the decimal point

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, 8.0010, 22.234]);
assert_eq!(Array::flat(vec![2., 4.6, 8.001, 20.]), arr.around(&Array::flat(vec![0, 1, 3, -1]).unwrap()));

fn rint(&self) -> Result<Array<N>, ArrayError>

Round elements of the array to the nearest integer

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, 8.0010, 22.234]);
assert_eq!(Array::flat(vec![2., 5., 8., 22.]), arr.rint());

fn fix(&self) -> Result<Array<N>, ArrayError>

Round to nearest integer towards zero

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, -1.6, -2.2]);
assert_eq!(Array::flat(vec![2., 4., -1., -2.]), arr.fix());

fn trunc(&self) -> Result<Array<N>, ArrayError>

Round to nearest integer towards zero

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, -1.6, -2.2]);
assert_eq!(Array::flat(vec![2., 4., -1., -2.]), arr.fix());

fn floor(&self) -> Result<Array<N>, ArrayError>

Return the floor of the input, element-wise

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, -1.6, -2.2]);
assert_eq!(Array::flat(vec![2., 4., -2., -3.]), arr.floor());

fn ceil(&self) -> Result<Array<N>, ArrayError>

Return the ceil of the input, element-wise

Examples

use arr_rs::prelude::*;

let arr = Array::flat(vec![2.01, 4.6, -1.6, -2.2]);
assert_eq!(Array::flat(vec![3., 5., -1., -2.]), arr.ceil());
