structures
strings
Answers
The answer is 'String'.
Answer:
So the answer is string
Explanation:
Numeric our usage of numeric data types to determine which data type best suits your design.
Representing Rational Numbers with the Fixed-Point Data Type
A fixed-point number has a fixed number of integer and fractional bits. The integer bits appear to the left of the binary point, and the fractional bits appear to the right of the binary point. Because you can specify the exact number of bits you want to use, the binary point, which is the binary equivalent of the decimal point, has a fixed position.
For example, you can configure LabVIEW to represent the rational number 0.5 as a fixed-point number with 8 total bits and 4 integer bits.
Rational Number Fixed-Point Equivalent
0.5 0000.1000
You also can configure LabVIEW to represent the same rational number as a fixed-point number with 16 total bits and 8 integer bits.
Rational Number Fixed-Point Equivalent
0.5 00000000.10000000
Fixed-point numbers differ from floating-point numbers in that floating-point numbers allow the number of integer and fractional bits to vary when you perform an operation on the floating-point number. In other words, the binary point can move, or float, in a floating-point number.
Note If you do not specify the exact number of bits you want to use to represent the fixed-point equivalent of a rational number, LabVIEW adjusts the number of bits to avoid data loss, if possible. LabVIEW cannot handle numbers longer than 64 bits.
Configuring Fixed-Point Numbers
To set a number to fixed-point representation, right-click the numeric object and select Representation from the shortcut menu to change the data type of the object. You can configure the encoding for fixed-point numbers. You also can specify whether to include an overflow status with fixed-point numbers and how Numeric functions handle overflow and rounding conditions for fixed-point numbers. To configure a fixed-point number, right-click a constant, control, indicator, or Numeric function and select Properties from the shortcut menu to display the Numeric Properties, Numeric Constant Properties, or Numeric Node Properties dialog box.
Encoding
Specify the binary encoding of a fixed-point number when you want the number to conform to a certain bit size.
Signed—The option that determines whether the fixed-point data is signed. If you select signed, the sign bit is always the first bit in the bit string that represents the data.
Unsigned—The option that determines whether the fixed-point data is unsigned.
Word length—The total number of bits in the bit string that LabVIEW uses to represent all possible values of the fixed-point data. LabVIEW accepts a maximum word length of 64 bits. Certain targets might limit data to smaller word lengths. If you open a VI on a target and the VI contains fixed-point data with larger word lengths than the target can accept, the VI contains broken wires. Refer to the documentation for a target to determine the maximum word length the target accepts.
Integer word length—The number of integer bits in the bit string that LabVIEW uses to represent all possible values of the fixed-point data, or, given an initial position to the left or right of the most significant bit, the number of bits to shift the binary point to reach the most significant bit. The integer word length can be larger than the word length, and can be positive or negative.
LabVIEW displays this configuration in the following format in the Context Help window when you move the cursor over a wire that carries fixed-point data:
1 Word length (8 bits)
2 Integer word length (10 bits)
3 Integer bits not stored
4 Binary point
If the integer word length is negative, LabVIEW does not store any integer bits and also does not store the number of fractional bits equal to the negative number, starting from the binary point. The following image represents a number with a word length of 8 and an integer word length of –2.
