Byte.From(value as any, optional culture as nullable text, optional roundingMode as nullable number) as nullable number 


Returns a 8-bit integer number> value from the given value. If the given value> is null, Byte.From returns null. If the given value is number within the range of 8-bit integer without a fractional part, value is returned. If it has fractional part, then the number is rounded with the rounding mode specified. The default rounding mode is RoundingMode.ToEven. If the given value is of any other type, see Number.FromText for converting it to number value, then the previous statement about converting number value to 8-bit integer number value applies.See Number.Round for the available rounding modes. An optional culture may also be provided (for example, "en-US").

Example 1

Get the 8-bit integer number value of "4".



Example 2

Get the 8-bit integer number value of "4.5" using RoundingMode.AwayFromZero.

Byte.From("4.5", null, RoundingMode.AwayFromZero)
