Issue is it's returning incorrect calculation, check screenshot!

Mhm.. Anymore information regarding this problem?

[Dokins]

Basically, if you check the screenshot you can see the issue, the tax rate should be 20%. What would you like to know?

I made a biggest mistake about the _: it took me time to find out a really really simple problem! Anyways here's the fully tested code, it works perfectly and doesn't return and incorrect values.

pawn Код:

CalculateTax(args1, Float:args2)
{
    if(0.0 > args2 > 100.0 && args1 < 0) return false; //return false if args2 is above 100% and below 0% same as the args1.
    return _:(args1 / 100 * args2);
}

Example Code

pawn Код:

public OnGameModeInit()
{
    printf("Tax 10%% of 1,000 = %.2f", CalculateTax(1000, 5.0) );
    printf("Tax 10%% of 1,000 = %.2f", CalculateTax(1000, 10.0) );
    printf("Tax 15%% of 1,000 = %.2f", CalculateTax(1000, 15.0) );
    printf("Tax 20%% of 1,000 = %.2f", CalculateTax(1000, 20.0) );
    printf("Tax 25%% of 1,000 = %.2f", CalculateTax(1000, 25.0) );
    printf("Tax 30%% of 1,000 = %.2f", CalculateTax(1000, 30.0) );
    printf("Tax 35%% of 1,000 = %.2f", CalculateTax(1000, 35.0) );
    printf("Tax 40%% of 1,000 = %.2f", CalculateTax(1000, 40.0) );
    printf("Tax 45%% of 1,000 = %.2f", CalculateTax(1000, 45.0) );
    printf("Tax 50%% of 1,000 = %.2f", CalculateTax(1000, 50.0) );
    printf("Tax 55%% of 1,000 = %.2f", CalculateTax(1000, 55.0) );
    printf("Tax 60%% of 1,000 = %.2f", CalculateTax(1000, 60.0) );
    printf("Tax 65%% of 1,000 = %.2f", CalculateTax(1000, 65.0) );
    printf("Tax 70%% of 1,000 = %.2f", CalculateTax(1000, 70.0) );
    printf("Tax 75%% of 1,000 = %.2f", CalculateTax(1000, 75.0) );
    printf("Tax 80%% of 1,000 = %.2f", CalculateTax(1000, 80.0) );
    printf("Tax 85%% of 1,000 = %.2f", CalculateTax(1000, 85.0) );
    printf("Tax 90%% of 1,000 = %.2f", CalculateTax(1000, 90.0) );
    printf("Tax 95%% of 1,000 = %.2f", CalculateTax(1000, 95.0) );
    return true;
}

CalculateTax(args1, Float:args2)
{
    if(0.0 > args2 > 100.0 && args1 < 0) return false; //return false if args2 is above 100% and below 0% same as the args1.
    return _:(args1 / 100 * args2);

PS: Try values like 93.55, I just tested the basic values and usually used

Thank you ever so much Patrick. Really appreciate it!
