`Fixed64` Data Type

Holds signed 64-bit (8-byte) fixed-point values with a default maximum of 15 digits to the left of the decimal point and 3 to the right. That is a range of −922,337,203,685,477.5808 – +922,337,203,685,477.5807.

Instructions

Default value: When you declare a variable of type Fixed64 and do not initialize it, its default value is zero (¤0.0).
Automatic conversions: Fixed64 widens to Real32, Real64, Real128, or Fixed128 without risk of overflow.
Type characters: You can put the suffix d64 (or D64) on the end of a number literal. And you can put the at-symbol (@) on the end of a name or number.

Fixed64 literal

prefix integer_part [ . fractional_part ]

integer_part [ . fractional_part ] suffix

Parts

prefix: One of these symbols: at-symbol (@) or currency symbol (¤). You can optionally follow the at-symbol with the currency symbol of a given culture. Examples include $, €, £, and ¥.; these symbols are ignored by the compiler. If you use a symbol, use the same one in all of your code.
integer_part: One to 18 decimal digits. For the default number of decimal digits, the maximum is 15 digits. You can use an underscore (_) to divide it into groups of digits.
fractional_part: One to 18 decimal digits. For the default number of decimal digits, the maximum is 4 digits. All digits after that are ignored.
suffix: One of these: the at-symbol (@) or the type suffix d64. You can also write the type suffix as D64.

Constructors

Fixed64(Optional digits As Int32 = 4): digits specifies the number of digits to the right of the decimal point. It must be between 1 and 19. The default is 4.

Shared methods and properties

Fixed64.Default As Fixed64: Returns the default value, ¤0.0.
Fixed64.Epsilon(Optional x As Fixed64) As Fixed64: Returns the smallest value more than ¤0.0. If x is not given, it returns ¤0.0001
Fixed64.Max(Optional x As Fixed64) As Fixed64: Returns the largest positive value for x. If x is not given, it returns ¤922_337_203_685_477.5807
Fixed64.Min(Optional x As Fixed64) As Fixed64: Returns the smallest negative value for x. If x is not given, it returns −¤922_337_203_685_477.5808
Fixed64.Parse(str As String, Optional #format As Format) As Fixed64: Tries to parse a string that shows as a number.; If #format is not given or is #Null, it uses the format of the local culture. Or you can make it clear with Format.UserLocale.
Fixed64.Size As Int32: Returns the number of available bytes. This is always 8.

Examples

Dim price As Fixed64 = @$1_199.99
Dim price@ = @$1_199.99
