1.3456
-1267
345

In reply to Prashant Soni:

How is the module receiving the values? Is it reading the file directly? If so, you can read it as a string, and then search for the period “.”.

If all you are concerned about is whether the value has a fractional component, you can read it as a real number, cast it to an int, and then subtract the real variable from the int variable. If the result is non-zero, you have fractional number.

In reply to Prashant Soni:

int file, code;
real value_real;
int  value_int;

file = $fopen("data.txt","r");
if (file==0) $error("fopen failed");
...
code = $fscanf("%g",value_real);
if (code == 1) // then we read one value
   begin
   value_int = value_real; // convert to integral 
   if (value_real - value_int == 0)
       $display("read integer");
   else
       $display("read real");
   end
