[amibroker] AlmostEqual bug ?

["freefall322" <freefall322@xxxxxxxxx>]

I'm using Amibroker 4.90 SE, ver. 4.90.5, build: may 24, 2007
I think this code reveals an "AlmostEqual" function bug:


//
// NiceBug.AFL
//
// this code shows that, among others, AlmostEqual(2,-2) is TRUE
// 
// output:
//
// AlmostEqual(2,-2) = 1
//  ii = -4   /    jj = 1    /    AlmostEqual( ii , jj ) = 1
//  ii = -2   /    jj = 2    /    AlmostEqual( ii , jj ) = 1
//  ii = -1   /    jj = 4    /    AlmostEqual( ii , jj ) = 1
//  ii = 1   /    jj = -4    /    AlmostEqual( ii , jj ) = 1
//  ii = 2   /    jj = -2    /    AlmostEqual( ii , jj ) = 1
//  ii = 4   /    jj = -1    /    AlmostEqual( ii , jj ) = 1
//

printf("AlmostEqual(2,-2) = %g\n",AlmostEqual(2,-2));
for (ii=-100;ii<=100;ii++) 
    for (jj=-100;jj<=100;jj++) {
        apple = AlmostEqual(ii,jj);
        if ((apple) AND (NOT(abs(ii-jj)<0.0001))) 
            printf(" ii = %g   /    jj = %g    /    AlmostEqual( ii ,
jj ) = %g\n",ii,jj,apple) ;
        }
