Module std::u32

use std::ascii;
use std::option;
use std::string;
use std::vector;

Function bitwise_not

Returns the bitwise not of the value. Each bit that is 1 becomes 0. Each bit that is 0 becomes 1.

public fun bitwise_not(x: u32): u32
Implementation 
public fun bitwise_not(x: u32): u32 {
    x ^ max_value!()
}

Function max

Return the larger of x and y

public fun max(x: u32, y: u32): u32
Implementation 
public fun max(x: u32, y: u32): u32 {
    std::macros::num_max!(x, y)
}

Function min

Return the smaller of x and y

public fun min(x: u32, y: u32): u32
Implementation 
public fun min(x: u32, y: u32): u32 {
    std::macros::num_min!(x, y)
}

Function diff

Return the absolute value of x - y

public fun diff(x: u32, y: u32): u32
Implementation 
public fun diff(x: u32, y: u32): u32 {
    std::macros::num_diff!(x, y)
}

Function divide_and_round_up

Calculate x / y, but round up the result.

public fun divide_and_round_up(x: u32, y: u32): u32
Implementation 
public fun divide_and_round_up(x: u32, y: u32): u32 {
    std::macros::num_divide_and_round_up!(x, y)
}

Function pow

Return the value of a base raised to a power

public fun pow(base: u32, exponent: u8): u32
Implementation 
public fun pow(base: u32, exponent: u8): u32 {
    std::macros::num_pow!(base, exponent)
}

Function sqrt

Get a nearest lower integer Square Root for x. Given that this function can only operate with integers, it is impossible to get perfect (or precise) integer square root for some numbers.

Example:

math::sqrt(9) => 3
math::sqrt(8) => 2 // the nearest lower square root is 4;

In integer math, one of the possible ways to get results with more precision is to use higher values or temporarily multiply the value by some bigger number. Ideally if this is a square of 10 or 100.

Example:

math::sqrt(8) => 2;
math::sqrt(8 * 10000) => 282;
// now we can use this value as if it was 2.82;
// but to get the actual result, this value needs
// to be divided by 100 (because sqrt(10000)).


math::sqrt(8 * 1000000) => 2828; // same as above, 2828 / 1000 (2.828)

public fun sqrt(x: u32): u32
Implementation 
public fun sqrt(x: u32): u32 {
    std::macros::num_sqrt!<u32, u64>(x, 32)
}

Function try_as_u8

Try to convert a u32 to a u8. Returns None if the value is too large.

public fun try_as_u8(x: u32): std::option::Option<u8>
Implementation 
public fun try_as_u8(x: u32): Option<u8> {
    std::macros::try_as_u8!(x)
}

Function try_as_u16

Try to convert a u32 to a u16. Returns None if the value is too large.

public fun try_as_u16(x: u32): std::option::Option<u16>
Implementation 
public fun try_as_u16(x: u32): Option<u16> {
    std::macros::try_as_u16!(x)
}

Function to_string

public fun to_string(x: u32): std::string::String
Implementation 
public fun to_string(x: u32): String {
    std::macros::num_to_string!(x)
}

Macro function max_value

Maximum value for a u32

public macro fun max_value(): u32
Implementation 
public macro fun max_value(): u32 {
    0xFFFF_FFFF
}

Macro function range_do

Loops applying $f to each number from $start to $stop (exclusive)

public macro fun range_do<$R: drop>($start: u32, $stop: u32, $f: |u32| -> $R)
Implementation 
public macro fun range_do<$R: drop>($start: u32, $stop: u32, $f: |u32| -> $R) {
    std::macros::range_do!($start, $stop, $f)
}

Macro function range_do_eq

Loops applying $f to each number from $start to $stop (inclusive)

Implementation 
public macro fun range_do_eq<$R: drop>($start: u32, $stop: u32, $f: |u32| -> $R) {
    std::macros::range_do_eq!($start, $stop, $f)
}

Macro function do
