Can you explain more and give an example? Do you mean integer values versus having a decimal part?

If so, you can test whether int(x)=x.

Hi Rick,

For e.g If I have the values for the column in the dataset as follows.

TOTAL_SUM

156

134.67

147

190.00

I need to find if the value of TOTAL_SUM is decimal then I have to do some manipulation based on that?

Hi Reeza,

For e.g the following decimal values have to be multiplied by 100.

134.67 -> 134.67 *100 -> 13467

Siva

Irrespective of the number of decimal places,if you want to multiply the number with 100 then you can use the following code.

data Want;

input Total_Sum;

if scan(Total_Sum,2,'.') ne " " then Total_Sum=Total_Sum*100;

cards;

156

134.67

147

190.00

;

If there is condition on which the number should be multiplied basing on the number of decimal places(i.e multiply with 100 if the value has two decimal places and 10 for 1 decimal place ....) then you can use the following code

data Want;

input Total_Sum;

if lengthn(scan(Total_Sum,2,'.')) ge 2 then Total_Sum=Total_Sum*100;

if lengthn(scan(Total_Sum,2,'.')) eq 1 then Total_Sum=Total_Sum*10;

cards;

156

156.1

134.67

147

190.00
