If the test is really short, you can make tables with either if/else or ?:
if ( $score >= 90 ) { $grade = 'A'; }
elsif ( $score >= 80 ) { $grade = 'B'; }
#...
else { $grade = 'F'; }
$grade = ( $score >= 90 ) ? 'A'
: ( $score >= 80 ) ? 'B'
: ( $score >= 70 ) ? 'C'
: ( $score >= 60 ) ? 'D'
: 'F';
Both of these degrade badly as the line length grows.
But, even if you like ifs (which I do mostly), tables are better than:
if ( $score >= 90 ) {
$grade = 'A';
}
elsif ( $score >= 80 ) {
$grade = 'B';
}
#...
