For compiling the code in “DevC++”, we have to press “F9” after the successful compilation; we then press the “F10” key for execution. The output is also shared below. The floating-point number array is shown in this image, and we can also note the values after the decimal point...
Floating Point in C Floating Point Puzzles Useful Links Prelogue 本节介绍了浮点数在计算机中的表示方法及其运算规则。相比于上一节的int,浮点数要弄清楚的概念比较多,不过弄明白后不得不佩服前人的智慧。 以下的内容大部分来自CMU的slides和CSAPP那本书,其间也有我自己的一些理解,如有谬误,敬请指正! Why Floati...
On a computer, an infinite precision number would require infinite memory to store, and we typically only have 4 or 8 bytes per value. This limited memory means floating point numbers can only store a certain number of significant digits -- any additional significant digits are either lost or ...

IEEE floating-point exceptions in C This page will answer the following questions. My program just printed out1.#INDor1.#INF(on Windows) ornanorinf(on Linux). What happened? How can I tell if a number is really a number and not aNaNor an infinity?
Thedecimaltype is appropriate when the required degree of precision is determined by the number of digits to the right of the decimal point. Such numbers are commonly used in financial applications, for currency amounts (for example, $1.00), interest rates (for example, 2.625%), and so...

Does anyone here know of a good web-page that explains floating point numbers, and how they are stored, well? I just realized that I have absolutely no idea how they work, when I had started thinking about how I would be able to compute the range of them. =) (Yes, I know there'...
