No, floating point is not supported by SystemCrafter SC Version 2.0. Floating point hardware implementations are extremely resource intensive and floating point algorithms can normally be more efficiently realised using integer arithmetic.

No, fixed point is not supported by SystemCrafter SC Version 2.0. Fixed point algorithms can always be modified to use integer arithmetic by applying suitable constant multipliers.

Have you tried EXAMINE STICK? The stick has a sharp point, which punctures the raft, which no longer floats. Don't bring the stick into the raft with you.

Obviously, any operation on a floating-point value, right? Well, yes and no.

A floating-point number is a number that has a fractional part; it is written with a decimal point, e.g.: 2.5, 3.141, -5.99. Floating point numbers are distinguished from integers, which have no fractional part. In Java, there are two types of floating-point numbers, those of type float and those of type double. Numbers of type double have higher precision than those of type float. By default, we will use double for floating-point numbers in CS111.

In the integer part, you devide by 2. In the decimal part, you multiply by 2 Decimal Binary 2 10 4 100 8 1000 16 10000 0.5 0.1 0.25 0.01 0.125 0.001 0.0625 0.0001 ... You should get my point now.

On many systems, you can define a function matherr which will be called when there are certain floating-point errors, such as errors in the math routines in <math.h>. You may also be able to use signal (see question 19.38) to catch SIGFPE. See also questions 14.9 and 20.6b.

FIST stores the value in ST to the specified memory location or register. Temporary-real values in registers are converted to the appropriate integer, BCD, or floating-point format as they are stored. With FSTP, FISTP, and FBSTP, the ST register value is popped off the stack. Memory operands can be 32-, 64-, or 80-bit real numbers for FSTP, or 16-, 32-, or 64-bit integers for FISTP.

You can enter a new floating point value in the fields of the Properties dialog. Just type the new value into the "value" field and press Enter (or Esc to abort). You can enter IEEE floating point values using the "IEEE" page or IBM floating point values using the "IBM FP" page. You can also change the byte-order using the "Big-endian" check box and enter 32-bit or 64-bit values depending on the format selected.

Why is cos(x) != cos(y) even though x == y? (Or sine or tangent or log or just about any other floating point computation) New!

Step 2: From the Arithmetic Operations popup dialog, select the arithmetic operation, whether the operation is with a scalar or image operand, and, for an image operand, the operand file name. Then, click OK.

In the old days Forth did not have floating-point numbers; instead, fixed-point arithmetic was used, usually on double-cell numbers. So, a decimal point indicated a double number (the position of the decimal point was stored in the variable DPL for potential use by fixed-boint software). In ANS Forth, a decimal point at the end indicates a double-cell number, and an E in the number indicates a floating-point number (when BASE is decimal). All other ways to write numbers are system-dependent.

The ksh syntax is now understood, i.e. let 'foo = 16#ff' or equivalently (( foo = 16#ff )) or even foo=$((16#ff)) The original syntax was (( foo = [16]ff )) --- this was based on a misunderstanding of the ksh manual page. It still works but its use is deprecated. Then echo $foo gives the answer '255'.

Q1: If I assign 0xFFFF to an integer, I get the message "arithmetic overflow in constant expression. Why doesn't it just treat it as -1? A1: As an int, this variable can only assume values of -32768 thru to 32767. The value 0xFFFF is equal to 65535, and is thus too big. If you really don't want signed values, use an unsigned int, or use -1, or use ~0. In general, if you want a value that has all bits set, and you don't want to be specific about how many bits that is, ~0 is good. e.g.

You can enable software assisted floating point numbers with -mieee. This will enable software assistance to correctly support denormalized numbers and exceptional IEEE values such as not-a-number and plus/minus infinity.

Here is a simple example (called "Sort Floats"): // Sort a list of floating point values #define USE_TI89 // Compile for TI-89 #define USE_TI92PLUS // Compile for TI-92 Plus #define USE_V200 // Compile for V200 #define MIN_AMS 100 // Compile for AMS 1.00 or higher #define SAVE_SCREEN // Save/Restore LCD Contents #include <tigcclib.

i) Please read chapter 8 of Super FinSim 8.4 Users Guide, which is available in .htm as well as in .pdf format on this WEB site. ii) The commercially available FinSim has a limitation of 127 bits of precision for trigonometric, and hyperbolic functions and of 82 bits for exponential and logarithmic functions. Customized versions may support enhanced precision.

In order to minimize size, versions of the printf and scanf functions without floating point support are linked by default. To enable floating point printf and scanf support, set the Floating Point I/O Supported property of your project to Yes.

Because handling it yourself is trivial, handling it in a fully integrated fashion is hard and I don't use floating point myself. Write your own callback routine. flag = { name = something; value = s; arg-type = string; arg-name = float; descrip = "floating point argument"; doc = "Example of an option with a floating point arg.
