How Can I Check Char is number?

Zeisen · **Author**

I want make a bool returns function string is number or not.
I want like:

Code:

char Hello[] = "123123";
bool result = IsNumber(Hello, sizeof(hello));
PrintToChatAll("result : %d", result); // it will print 1

Code:

char Hello[] = "World!";
bool result = IsNumber(Hello, sizeof(hello));
PrintToChatAll("result : %d", result); // it will print 0

PHP Code:


			
bool IsStringNumeric(const char[] str)
{
    int len = strlen(str);
    for (int i = str[0] == '-' ? 1 : 0; i < len; i++)
        if (!IsCharNumeric(str[i]))
            return false;
    return true;
}

Note: "-" string also will valid. Add check if needed.
