Csh floating point arithmetic
http://easck.com/cos/2024/0923/338231_8.shtml Webfloating point arithmetic - bc. Sometimes we might do integer arithmetic with @ but floating point arithmentic, trignometry etc. is not available with this, so we might have to use gawk or bc (basic calculator). Type: bc -l. Now type in some floating point arithmetic: 10*10. 1-5. 1+1. 2/3. 2^4. c(10*3.1416/180.)

WebFloating-point representations are not necessarily unique. For example, both 0.01 × 101 and 1.00× 10-1 represent 0.1. If the leading digit is nonzero (d 0 ≠ 0 in equation (1) … WebSep 3, 2015 · This standard specifies interchange and arithmetic formats and methods for binary and decimal floating-point arithmetic in computer programming environments. …
WebJan 4, 2024 · This may come as a surprise, but Bash only supports integer arithmetic natively. If you need to perform calculations on floating point numbers, you will need to call out to a utility program like bc or Python. As a quick proof to yourself, try multiplying integers, then do the same with floating point numbers. $ ... Bash: Performing floating … 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.
WebFeb 1, 2010 · You are correct - you need awk, perl, bc, etc. to do floating point arithmetic. Not shell - shell does not support FP. Correct (it's not possible). Some newer shells, like ksh93 support floating point arithmetic, but for portability it's probably best to use bc.
