WebAug 13, 2014 · There's no reason to be using expr for arithmetic in modern shells.. POSIX defines the $((...)) expansion operator. So you can use that in all POSIX compliant shells (the sh of all modern Unix-likes, dash, bash, yash, mksh, zsh, posh, ksh...).. a=$(( 3 * (2 + 1) )) a=$((3*(2+1))) ksh also introduced a let builtin which is passed the same kind of … 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.)

Arithmetic in floating point
WebMar 4, 2024 · The division of two integers in Python2 results in an integer, but it can be a floating-point number in Python3. It’s possible to set the precision of the result in Python3: $ python3 -c 'x=60; y=-9; print("{:.4f}".format(x/y))' -6.6667. Python has the float data type, so the inputs of the division can be floating-point numbers: WebJan 19, 2007 · * Procedures involving heavy-duty math operations, especially floating point arithmetic, arbitrary precision calculations, or complex numbers (use C++ or FORTRAN instead)” So the work-arounds are indirect and perhaps (for some) counter-intuitive.
