fromString

public static byte fromString(string numberAsStr)

The byte equivalent of the string value or zero (0) if the string is not a numeric value.

Parameters

numberAsStr

The string value to convert.

Converts a string to a byte value.

import System;

byte x = UInteger8.fromString("100");
Console.log(x); // 100

If the string being converted is not a valid integer value, zero (0) is returned.

import System;

byte x = UInteger8.fromString("abc");
Console.log(x); // 0

If the string being converted is numeric but does not fit into the byte data range [ 0, 255 ] (inclusive), the value will be wrapped: if the value exceeds the byte maximum (255) by one, it will wrap around to the byte minimum (0); if the value exceeds the byte maximum by two, it will wrap around to the byte minimum plus one (1); and so on.

import System;

byte exceedByOne = UInteger8.fromString("256");
Console.log(exceedByOne); // 0
byte exceedByTwo = UInteger8.fromString("257");
Console.log(exceedByTwo); // 1
byte exceedByThree = UInteger8.fromString("258");
Console.log(exceedByThree); // 2
