changed code (fyi - not familiar with bc)
Yes I am trying to retain the decimal place to 1ooth place (i.e. 99.99)

Hope this helps.

here are the parts of code I changed.
Code:
#
#get total minutes for the month
#

MNTHMINS=$('scale = 2; 1440*DAYS' | bc)


#
#get total outage minutes
#

OUTMINTOT=0
OUTMINTOT=$('scale = 2; OUTMIN1+OUTMIN2+OUTMIN3+OUTMIN4+OUTMIN5' | bc)
echo $OUTMINTOT

#
#calculate percentage of uptime
#

PRCNT1=$('scale = 2; MNTHMINS-OUTMINTOT' | bc)
echo $PRCNT1
PRCNT2=$('scale = 2; PRCNT1/MNTHMINS' | bc)
echo $PRCNT2
PRCNT3=$('scale = 2; PRCNT2*100' | bc)
echo $PRCNT3

here is the error output -
Code:
+ + bc
+ scale = 2; 1440*DAYS
./calctotmin.ksh[48]: scale = 2; 1440*DAYS:  not found.
MNTHMINS=
+ OUTMINTOT=0
+ + scale = 2; OUTMIN1+OUTMIN2+OUTMIN3+OUTMIN4+OUTMIN5
+ bc
./calctotmin.ksh[56]: scale = 2; OUTMIN1+OUTMIN2+OUTMIN3+OUTMIN4+OUTMIN5:  not found.
OUTMINTOT=
+ echo 0
+ + scale = 2; MNTHMINS-OUTMINTOT
+ bc
./calctotmin.ksh[63]: scale = 2; MNTHMINS-OUTMINTOT:  not found.
PRCNT1=
+ echo 0
+ + bc
+ scale = 2; PRCNT1/MNTHMINS
./calctotmin.ksh[65]: scale = 2; PRCNT1/MNTHMINS:  not found.
PRCNT2=
+ echo 0
+ + bc
+ scale = 2; PRCNT2*100
./calctotmin.ksh[67]: scale = 2; PRCNT2*100:  not found.
PRCNT3=
+ echo 0
+ exit 0

NAME

       svm-scale - scale data to a restricted range as preprocessing for SVM training

SYNOPSIS

       svm-scale [ -l lower ] [ -u upper ] [ -y y_upper ] [ -s save_filename ] [ -r restore_filename ] datafilename

DESCRIPTION

       svm-scale  reads  the  given  datafilename (a training or testing data file as specified in svm_train(1) or svm_predict(1) ) and scales all
       dimensions to the given ranges.

OPTIONS

       -l lower
	      lower is the lowest (minimal) value allowed in each dimension.  It defaults to -1.

       -u upper
	      upper is the highest (maximal) value allowed in each dimension.  It defaults to 1.

       -y y_lower
	      y_lower is a boolean value (0 or 1) indicating whether or not y-values (targets) should be scaled.  It defaults to 0.

       -s save_filename
	      save_filename indicates the filename to save the scaled data to.

       -r restore_filename
	      restore_filename indicates the filename reserved to hold the original (unscaled) data in case there is a need to restore.

FILES

       datafilename must be a training or testing dataset.
