What should be the value returned by the .BoolValue property getter when the related ConVar is 0.0<x<1.0?
I'm asking because I have seen some scripts (ex. SuperVersus) that use this snippet

ConVar TankHpMulti;
...
    TankHpMulti    = CreateConVar("director_tank_hpmulti","0.25","Tanks HP Multiplier (multi*(survivors-4)). Requires director_auto_difficulty 1", CVAR_FLAGS,true,0.00,true,1.00);
...
    if (TankHpMulti.BoolValue){   // if not 0
            int TankHP = RoundFloat(4000.0*TankHp_Multi);
            FindConVar("z_tank_health").IntValue = TankHP;
    }

However after I noticed that the last part of the code is never called despite director_tank_hpmulti > 0, I added some debug prints and have seen that any value < 1 (without counting 0) returns false.
Who is doing incorrectly there?

you should probably check if the ConVar's FloatValue is greater then 0

.FloatValue is returning the expected value, however it's those .BoolValue s that are bugging me because the script I'm analyzing wasn't written by me and looking at the API documentation of SM it doesn't specify anything about when .BoolValue should return true and when it returns false, leaving it as an undefined behaviour in my eyes

.BoolValue, as well as other aspects of the transitional syntax, compiles to the same code as the old syntax. So it's the same as using:

https://sm.alliedmods.net/new-api/convars/GetConVarBool
https://sm.alliedmods.net/new-api/convars/SetConVarBool

From what I remember from what I've experienced, the only values that GetConVarBool should evaluate to FALSE are 0 (and its equivalents, 0.0, -0.0, etc.) as well as actually putting the word "false" into the ConVar. None of that is true.

That code is broken anyway since its multiplying by the ConVar variable itself, probably missing a FloatValue.

As for BoolValue, the engine calculates it from IntValue, which is truncated from FloatValue, so: 0.9 ~= 0 ~= false, 1.1 ~= 1 ~= true.

The float value was declared right above the if expression as

float TankHp_Multi = 1 + TankHpMulti.FloatValue*extrasurvivors;

and I didn't include it in my post for sake of clarity.
I agree that the similar name is confusing but again I didn't write the plugin.

This is all what I needed to know, thanks.
