std::number
Number Module
Numeric helpers built on top of std::math.
Namespaces
Number — absolute value
| Input type | Return type | Notes |
|---|---|---|
i8 |
u8 |
Widens to i16 internally |
i16 |
u16 |
Widens to i32 internally |
i32 |
u32 |
Widens to i64 internally |
i64 |
u64 |
Handles MIN without overflow |
f32 |
f32 |
Simple negation |
f64 |
f64 |
Delegates to Math::fabs |
All overloads are @extension methods and can be called as Number::abs(value).
Float — rounding helpers
| Method | Types | Description |
|---|---|---|
toFixed |
f64, f32 |
Round to digits decimal places |
round |
f64, f32 |
Round to nearest integer |
floor |
f64, f32 |
Round toward negative infinity |
ceil |
f64, f32 |
Round toward positive infinity |
f32 overloads widen to f64, delegate to Math, then narrow back.
Example
import Number, Float from "std::number";
import Io from "std::io";
import String from "std::string";
function main(): i32 {
let a: u32 = Number::abs(-42);
let b: f64 = Float::toFixed(3.141592, 2);
let c: f32 = Float::ceil(2.2);
Io::println(String::toString(a));
Io::println(String::toString(b));
Io::println(String::toString(c));
return 0;
}
namespace FloatFloating-point formatting and rounding helpers.
Functions in this namespace complement Number with operations specific to
decimal floating-point presentation.
Functions
function ceil(value: f64): f64Rounds up to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::ceil(2.1);
function ceil(value: f64): f64Rounds up to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::ceil(2.1);
function floor(value: f64): f64Rounds down to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::floor(2.9);
function floor(value: f64): f64Rounds down to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::floor(2.9);
function round(value: f64): f64Rounds to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::round(2.6);
function round(value: f64): f64Rounds to the nearest integer.
Example
import Float from "std::number";
let x: f64 = Float::round(2.6);
function toFixed(value: f32, digits: u32): f32Rounds value to digits decimal places.
Example
import Float from "std::number";
let x: f32 = Float::toFixed(3.141592 as f32, 2);
function toFixed(value: f32, digits: u32): f32Rounds value to digits decimal places.
Example
import Float from "std::number";
let x: f32 = Float::toFixed(3.141592 as f32, 2);
namespace NumberNumeric helpers for integer and floating-point values.
The namespace currently provides absolute-value overloads that avoid signed overflow for minimum integer values by returning unsigned magnitudes.
Functions
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
function abs(value: f64): f64Returns the absolute value of an f64.
Example
import Number from "std::number";
let x: f64 = Number::abs(-3.5);
