Csh floating point arithmetic
WebNov 28, 2024 · Floating-point numbers have several distinct "ranges": Standard/Normal arithmetic; Subnormal arithmetic; Infinite arithmetic; NaN arithmetic; Zero arithmetic; For instance, if I add any normal number to an infinite number, I need to get an infinite number back. If I add two large enough subnormals, I should get a normal number. WebThe floating point numbers are pulled from a file as a string. The format of the file is as follows: 1.5493482,3.49384,33.284732,23.043852,2.2384... 3.384,3.282342,23.043852,2.23284,8.39283... . . . Here is some simplified sample code I …

WebJul 22, 2024 · A1: 1.2E+200 B1: 1E+100 C1: =A1+B1. The resulting value in cell C1 would be 1.2E+200, the same value as cell A1. In fact if you compare cells A1 and C1 using the IF function, for example IF (A1=C1), the result will be TRUE. This is caused by the IEEE specification of storing only 15 significant digits of precision.
