What is Extended type in delphi?
The Extended type is an Intel standard floating-point type that uses 10 bytes to store a sign bit, a 15-bit exponent, and a 64-bit mantissa. Delphi raises runtime error 6 ( EInvalidOp ) if you try to use an invalid bit pattern as a floating-point number.
What is an integer in Delphi?
Integer represents a subset of the integer numbers. The range for the Integer type is from -2147483648 through 2147483647 . The size of Integer is 32 bits across all 64-bit and 32-bit platforms.
What are real numbers in Delphi?
DELPHI: Numbers Variables are declared as integers if they use whole numbers (for example 23 or 765) and real if they have decimal fractions (for example 2.63 or 0.46544).
What is real in Delphi?
A real type defines a set of numbers that can be represented with the floating-point notation.
What is single in Delphi?
The Single type is an IEEE standard floating-point type that uses 4 bytes to store a sign bit, an 8-bit exponent, and a 23-bit mantissa. An exponent of all 1 bits represents infinity (mantissa is zero) or not-a-number (mantissa is not zero).
What is cardinal in Delphi?
The Cardinal type is an unsigned integer subrange whose size is the natural size of an integer. In Delphi 5, the size is 32 bits, but in future versions of Delphi, it might be larger. Use LongWord for an unsigned integer type that must be 32 bits, regardless of the natural size of an integer.
What is FloatToStr in Delphi?
FloatToStr converts the floating-point value given by Value to its string representation. The conversion uses general number format with 15 significant digits. For greater control over the formatting of the string, use the FloatToStrF function.
What does ORD do in Delphi?
The Ord function returns the ordinal value of a character or enumeration as a non-negative integer.
What is System single in C#?
The Single value type represents a single-precision 32-bit number with values ranging from negative 3.402823e38 to positive 3.402823e38, as well as positive or negative zero, PositiveInfinity, NegativeInfinity, and not a number (NaN).
What is the size of LongWord?
32 bits
In short: Longint and Longword are fixed size integers, the former signed, the latter unsigned, and both usually 32 bits in size.
What is cardinal type?
What is AnsiChar?
AnsiChar values are byte-sized (8-bits) characters ordered according to the locale character set, which is possibly multibyte. The first 256 Unicode characters correspond to the ANSI characters.
Which is the best extended set in Delphi?
The Single type is the smallest and fastest, but with worst capacity and precision. The Double type has medium storage, speed, capacity and performance. A Extended set to its highest value is treated as Infinity.
How many digits does a Delphi extended command support?
It supports approximately 19 digits of precision in a range from 3.37 x 10 -4932 to 1.18 x 10 4932 . The Single type is the smallest and fastest, but with worst capacity and precision. The Double type has medium storage, speed, capacity and performance. A Extended set to its highest value is treated as Infinity.
How are integer and extended types incompatible in Delphi?
Delphi: Incompatible types: ‘integer’ and ‘extended’. I need to make a program that works out the amount you will get paid for the hours you worked.
What are the types of data in Delphi?
Real Types. Delphi has several floating-point types. The basic types are Single, Double, and Extended Single and Double correspond to the standard sizes for the IEEE-754 standard, which is the basis for floating-point hardware on Intel platforms and in Windows.
