#include <a_samp>

main() { printf("value: %i", strval("test")); }

Oh..lazy people.

Re: strval - Fergy - 19.03.2013

Oh no... Is there any function like IsString ?

Re: strval - Jstylezzz - 19.03.2013

You can make one, try this for example:

pawn Код:

IsNumeric(const string[])
{
    for (new i = 0, j = strlen(string); i < j; i++)
    {
        if (string[i] > '9' || string[i] < '0') return 0;
    }
    return 1;
}

Use this to check if a string is numeric.

I recommend using the version from y_utils as it's about 3 times as fast (Benchmarked with 10000 loops, your version took 9ms while this one only 3ms - the difference is pretty unnoticable, but still):

pawn Код:

stock isnumeric(str[])
{
    new
        ch,
        i;
    while ((ch = str[i++])) if (!('0' <= ch <= '9')) return 0;
    return 1;
}
