`Fixed128` Data Type

Holds signed 128-bit (16-byte) fixed-point values with a default maximum of 29 digits to the left of the decimal point and 10 to the right. That is a range of −17,014,118,346,046,923,173,168,730,371.5884105728 – +17,014,118,346,046,923,173,168,730,371.5884105727.

Instructions

Default value: When you declare a variable of type Fixed128 and do not initialize it, its default value is zero (¤0.0).
Automatic conversions: Fixed128 widens to Real32, Real64, or Real128 without risk of overflow.
Type characters: You can put the suffix d128 (or D128) on the end of a number literal. But there are no type characters for names.

Fixed128 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 38 decimal digits. For the default number of decimal digits, the maximum is 29 digits. You can use an underscore (_) to divide it into groups of digits.
fractional_part: One to 39 decimal digits. For the default number of decimal digits, the maximum is 10 digits. All digits after that are ignored.
suffix: One of these: the at-symbol (@) or the type suffix d128. You can also write the type suffix as D128.

Constructors

Fixed128(Optional digits As Int32 = 10): digits specifies the number of digits to the right of the decimal point. It must be between 1 and 39. The default is 10.

Shared methods and properties

Fixed128.Default As Fixed128: Returns the default value, ¤0.0.
Fixed128.Epsilon(Optional x As Fixed128) As Fixed128: Returns the smallest value more than ¤0.0. If x is not given, it returns ¤0.0000000001.
Fixed128.Max(Optional x As Fixed128) As Fixed128: Returns the largest positive value for x. If x is not given, it returns ¤17_014_118_346_046_923_173_168_730_371.5884105727.
Fixed128.Min(Optional x As Fixed128) As Fixed128: Returns the smallest negative value for x. If x is not given, it returns -¤17_014_118_346_046_923_173_168_730_371.5884105728.
Fixed128.Parse(str As String, Optional #format As Format) As Fixed128: 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.
Fixed128.Size As Int32: Returns the number of available bytes. This is always 16.
