NaN Meaning In Javascript
Javascript allows you to represent numbers such as integer and floating-point numbers. These numbers have a special value called NaN. In a programming language, NaN stands for Not a Number.
NaN Meaning In Math
Do you know what does NaN mean in math? NaN is a short form for Not a Number in mathematics. It is an undefined or unrepresentable value used in floating-point calculations. For example, when you search for the square root of a negative number, a NaN will be displayed in the results.

Why did the forward room fire the torpedoes?
There was a slight tendency to fire torpedoes from the forward room instead of the aft room, because the forward room could fire a salvo of six, whereas the aft room could only fire a salvo of four. Also, in some attacks, there was not time to swing the boat to bring the stern tubes to bear.
What does nan mean in computer?
NaN (Not a Number) is what many computer programs cause to be printed if the number is not a valid number. it could result from a divide by zero operation, or simply a value not entered to a program. Likely what has happened is the programmer did not trap an illegal value so the computer program resorted to its default presentation.
Can you blow air to submerge a ballast tank?
First off, you don’t blow air to submerge ; you open the Main Ballast Tank vents (they’re operated hydraulically normally, but can be cycled manually if needed), which lets water come in through the bottom of the MBT’s, forcing air out through the vents on the main deck topside.
Why were there fewer torpedoes in the rear of the submarine?
The reason there were fewer torpedoes in the rear was that the sub tapered in that direction, and also had propeller shafts that took up space. A submarine commander never wanted to end up with a “one-ended boat”, i.e., a boat that had torpedoes only fore or aft.
What happens if one end of a boat is firing all the torpedoes?
If one end of the boat was doing all the firing, the other end would be discouraged, and have their pride hurt. Often times, if a boat was in danger of becoming one-ended, the lead torpedoman from the end that hadn't fired any torpedoes yet would approach the captain and ask him to fire torpedoes from their room.
Did the US torpedo boat have to swing all the way?
However, the boat didn’t have to swing all the way, since US torpedoes had gyros that could turn the torpedo in the direction it needed to go. Also, there were directives from the submarine command that stated that certain ships should be fired at with a certain number of torpedoes.
Can a submarine fire from the stern?
However, if the submarine is on station ahead of the target and has a little time, it is just as easy to fire from either room. So he could fire from the stern before the target reached him, then swing his boat and be able to fire from the forward tubes before the target had gone too far past him.
What does nan mean in math?
In computing, NaN ( / næn / ), standing for Not a Number, is a member of a numeric data type that can be interpreted as a value that is undefined or unrepresentable, especially in floating-point arithmetic.
When was the NaN introduced?
Systematic use of NaNs was introduced by the IEEE 754 floating-point standard in 1985, along with the representation of other non-finite quantities such as infinities . In mathematics, zero divided by zero is undefined as a real number, and is therefore represented by NaN in computing systems. The square root of a negative number is not ...
Is NaN the same as infinity?
In floating-point calculations, NaN is not the same as infinity, although both are typically handled as special cases in floating-point representations of real numbers as well as in floating-point operations.
What is the predicate for a NaN operand?
The other standard comparison predicates are all signaling if they receive a NaN operand. The standard also provides non-signaling versions of these other predicates. The predicate isNaN ( x) determines if a value is a NaN and never signals an exception, even if x is a signaling NaN.
What happens if an operation produces an exception condition and traps are not masked?
If an operation can produce an exception condition and traps are not masked then the operation will cause a trap instead. If an operand is a quiet NaN, and there is also no signaling NaN operand, then there is no exception condition and the result is a quiet NaN.
What is a quiet NAN?
Quiet NaN. Quiet NaNs, or qNaNs, do not raise any additional exceptions as they propagate through most operations. The exceptions are where the NaN cannot simply be passed through unchanged to the output, such as in format conversions or certain comparison operations.
What is the quiet bit on a processor?
most processors (including those of the Intel and AMD 's x86 family, the Motorola 68000 family, the AIM PowerPC family, the ARM family, the Sun SPARC family, and optionally new MIPS processors) set the signaling/quiet bit to non-zero if the NaN is quiet, and to zero if the NaN is signaling.
What does nan mean on Fitbit?
NaN is a computer error for "not a number". That is usually a problem with that particular clock face. Switching to another clock face usually fixes it. The ones "by Fitbit" seem to be the most reliable to avoid such problems.
Who is the Fitbit Community Council?
Fitbit Community Council members are a select group of volunteers who share support knowledge on the forums and advocate for the betterment of Fitbit products and services.
