Bash: Performing floating arithmetic using bc - Fabian Lee

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. WebApr 21, 2024 · I am trying to add two floating point numbers together using shell script.

Arithmetic in floating point

WebFloating-point types may support special values: infinity (positive and negative), see INFINITY; the negative zero, -0.0.It compares equal to the positive zero, but is meaningful in some arithmetic operations, e.g. 1.0 / 0.0 == INFINITY, but 1.0 /-0.0 ==-INFINITY) not-a-number (NaN), which does not compare equal with anything (including itself). Multiple bit … WebJun 15, 2024 · The sign is a single bit – 0 if the number is positive, 1 if negative. The significand (also called the mantissa) is a fixed-point number in the range (1, 2].It might be something like 1, 1.0625 or 1.984375, but it can’t be 2. What it intuitively does is it “fine-tunes” the value within the range set by the sign and exponent. WebFloating-point representations are not necessarily unique.

Some newer shells, like ksh93 support floating point arithmetic, but for portability it's probably best to use bc. WebA floating-point (FP) number is a kind of fraction where the radix point is allowed to move. If the radix point is fixed, then those fractional numbers are called fixed-point numbers. The best example of fixed-point numbers are those represented in commerce, finance while that of floating-point is the scientific constants and values.

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.
