you cannot do float math natively with most shells.

ragha.sh 3 4
ragha.sh 9 10
ragha.sh 35 36

ragha.sh:
Code:
#!/bin/ksh

typeset -i num_tasks="${1}"
typeset -i max_tasks="${2}"

typeset threshold='.95'

echo "num->[$num_tasks]"
echo "max->[$max_tasks]"

per_load=$(echo "scale=2; $num_tasks / $max_tasks" | bc)

echo "per_load->[$per_load]"

if [ "$(echo "if (${per_load} > ${threshold}) 1" | bc)" -eq 1 ]; then
   echo "not good"
fi
