Hello,

How can I check if a value is a float or if it's an integer?

I need something similar like the PHP Function: is_float($x) and is_int($x)
http://php.net/manual/en/function.is-float.php
http://php.net/manual/en/function.is-int.php

Thanks in advance

Give a context/code where you need that.

Situation #1:

someFunction(any:value) {
    // Do something with value
}

// Call with an integer
someFunction(1337);
// Call with a float
someFunction(13.37);

In this case, you would need to add another parameter to specify if the provided value is float or integer.

Situation #2:
Trying to determine if a string is a float or integer.

stock bool:is_str_float(const string[], bool:require_decimal=true) {
    new count, pos, ch;
    while((ch = string[pos++])) {
        if(ch == '.') {
            if(++count > 1) {
                return false;
            }
        }
        else if(!('0' <= ch <= '9')) {
            return false;
        }
    }
    return (!require_decimal || count == 1);
}

Thanks for your replys, but these can't help me. I should provide more information I guess.

I'm trying to add it into a calculator I made, http://forums.alliedmods.net/showthread.php?t=172415

PHP Code:

format(szArg, charsmax(szArg), "%d", mathEvaluateEquation(szArg)) 


I want to check if the output of mathEvaluateEquation(szArg) is an integer value or if it's a float so I can print out the correct value when a player is dividing something which will contain decimals.

In CS it could be something like:

PHP Code:

new Float:Amount = 5.2
if( Amount == float(floatround(Amount)) ) 


floatround will make Amount to 5, float makes it back to 5.0
so: 5.2 != 5.0

Means its a float

A function like that should always return a float and therefore you can always use something like "%.2f". You should post that entire mathEvaluateEquation() function if you want more accurate help.

I am aware that I can use %.2f in this case, but it would be better if i just had plain numbers instead of decimals when it's an integer value.

Did you try Xalus' method?
