Can we write a computer program which will find the largest and Smallest Decimal Number in a List? Example: 3.2,4.3,-2.1,7.3,5.4,-6.3,8.2,1.1,0.8 Thanks & Regards, Prashant S Akerkar

If smallest is most negative then: In Excel: Max( 3.2,4.3,-2.1,7.3,5.4,-6.3,8.2,1.1,0.8 ) and Min( 3.2,4.3,-2.1,7.3,5.4,-6.3,8.2,1.1,0.8 ) If smallest means closest to zero, then it becomes marginally more complicated.

If you are asking for a program that uses only the most simple commands then start by setting "max" and "min" equal to a number in the list. Then loop through the list, comparing each number to "max" and "min". If the number is larger than "max", set "max" equal to it. If the number is less than "min", set min equal to it. Suppose your list of numbers is the array "numbers[]" with n members. Then float max, min; max= min= numbers[0]; for (i=0;i< n;i++) { if (numbers[i]> max) then max= numbers[i]; if (numbers[i]< min) then min= numbers[i]; }
