For loop in awk, a bug or something else?

Seems for loop in awk has bug?

For first awk, i expect to get 4 output: 1.5, 1.4, 1.3, 1.2, but there are only 3.

$ awk 'BEGIN {for (i=1.5;i>=1.2;i-=0.1) print i}'

$ awk 'BEGIN {for (i=15;i>=12;i-=1) print i}'

igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
