fromStringOr

public static byte fromStringOr(string numberAsStr, byte defaultValue)

The byte equivalent of the string value or the provided default value if the string is not valid.

Parameters

numberAsStr

The string value to convert.

defaultValue

The default value to return if the conversion fails.

Converts a string to its equivalent byte value or the provided default value if the conversion fails.

import System;

byte x = UInteger8.fromStringOr("100", 101);
Console.log(x); // 100 // conversion succeeded
byte y = UInteger8.fromStringOr("abc", 101);
Console.log(y); // 101 // conversion failed so default value returned

If the string being converted is numeric but does not fit into the byte data range [ 0, 255 ] (inclusive), the default value will be returned.

import System;

byte fits = UInteger8.fromStringOr("255", 100);
Console.log(fits); // 255
byte exceedByOne = UInteger8.fromStringOr("256", 100);
Console.log(exceedByOne); // 100
byte exceedByTwo = UInteger8.fromStringOr("257", 100);
Console.log(exceedByTwo); // 100
byte exceedByThree = UInteger8.fromStringOr("258", 100);
Console.log(exceedByThree); // 100
