![]() ![]() Note that bc itself doesn't understand the engineering notation, you have to write: $ eng 20 "1. They are similar to those used by the printf function in the C programming language. These operators control notation, alignment, significant digits, and so on. Engineering notation allows the numbers to explicitly match their. Here with the first argument being taken as the scale: $ eng 2 1/3 Formatting Text To convert data to text and control its format, you can use formatting operators with common conversion functions, such as num2str and sprintf. Though similar in concept, engineering notation is rarely called scientific notation. The mantissa has 5 significant digits in the short. (with a 1e-15 shift to offset rounding errors when calculating log10(n) for the exponent for values of n like 0.001) The number to be represented is split between a mantissa and an exponent (power of 10). Or as a POSIX shell function using POSIX bc, so allowing arbitrary precision: eng() ( (though that's not specific to that eng function) It's also limited to integer numbers up to 2 63-1 (8Ei - 1)).Īs to how to implement it by hand, with zsh: eng(). (note however that you can't change the precision and the transition from Ki to Mi for instance is at 1000 Ki, not 1024 Ki which can be surprising if you're used to the GNU format (like in GNU ls -lh). format short e, Five digits plus exponent. suffixes and %#i for Ki/Mi/Gi ones: $ printf '%#d\n' 105000000 $((2**22)) Numeric Display Format format short, Four decimal digits (default). With the printf builtin of ksh93, you can also use %#d for K/M/G. $ LC_NUMERIC=ps_AF.UTF-8 printf "%'.0f\n" 105000000 Number format Follow 6 views (last 30 days) Show older comments Poul Reitzel on Dear Matlab Community I am facing a problem to convert a row of numbers to a string in a specific format. ![]() MATLAB is a programming platform designed specifically for engineers and. ![]() $ LC_NUMERIC=de_CH.UTF-8 printf "%'.0f\n" 105000000 When used in a format specifier string, it puts the following stuff on a new. With several printf implementations, you can use %'f to output thousand separators in locales that have one: $ LC_NUMERIC=en_GB.UTF-8 printf "%'.0f\n" 105000000 A formatting operator can have a maximum of six fields-the conversion character, subtype, precision, field width, flags, and numeric identifier. Note that POSIX doesn't even guarantee printf '%E\n' 123 to work at all as support for floating point formats is optional. I don't know of any printf implementation that does. ![]()
