[graalvm-users] Question about GraalVM, Java 17 and Floating Point Arithmetic.

Dear GraalVM,

I would like to know how GraalVM Java performs.

-Is it compatible with Free Open Source Java libraries,
or other Java libraries, out there?

-Has GraalVM removed the phenomenon of Java
Floating Point denormal and pronormal values?
Consider the following Java code snippet:

package JavaApplication;
import static java.lang.System.*;
public class Start
    public static void main(String ...args)
    out.println("Program has started...");
    double a = 0.1;
    double b = 0.1;
    double c = a*b;
    out.println(c == 0.01);
    float d = 0.01F;
    float e = 0.01F;
    float f = d*e;
    out.println(f == 0.01);
    out.println("Program has Finished.");

-What I need is a version of Java 17 that has the same
free-for-all-use license model as OpenJDK17, but has
removed the phenomenon of denormal and pronormal
values, of all defaulting arithmetic, systematically,
involving float and double, and their objects.

-Will GraalVM run the included code fragment,
outputting the generally expected results,
printing true and not false?
