floating point binary calculator

Let's talk about php floating point exact calculation, php floating point number Bc is short for Binary Calculator. Bc * function parameters are all operands plus an optional [int scale], such as string bcadd (string $ left_operand, string $

Description of UseBash has built-in support for integer arithmetic, but it does not support floating-point operations, and the BC command can be very handy for floating-point operations, and of course integer arithmetic is no longer spoken. The

Remember writing test cases a long time ago and inadvertently discoveringDouble c=2.31;Double d=0.1;System.out.println (C/D);The final output is unexpectedly 23.099999999999998, rather than the simple 23.1, it is obvious that such results will be

The percentage of CPU, memory usage of the process seen through the top command is a floating-point number, and I need to process it while writing the script, so I learned a few things and summarized as follows. In fact, the Shell (here is bash)

In the operation of floating-point numbers in PHP, a hole was encountered, which did not get the expected result, as follows: $a = 69.1;$b = $a *100;$c = $b-6910; What do you think the value of $c is? The value $c output is -9.0949470177293E-13.
