Hello friends, I am confused about the single and double precision in Java.What they are used for and what's the difference between them.If anyone can tell me,i will be very thankful. Thanks in advance. Sunanda
Hi, Sunanda! The single and double precision refer to the IEEE 754-1985 standard. For Java the following is true: single prec -> 32 bits -> Min = 1.43e-45 -> Max = 3.4e38 Double prec -> 64 bits -> Min = 4.942-324 -> Max = 1.8e308 As you can see, double precision can hold much larger values then the single precision. You also use double the amount of memory for double versus single. Regards, Manfred.

Thanks for the description,but there is one more doubt,what about the decimal places in both ,the single and double precision. Thanks in advance. Sunanda
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
