TryParse(ReadOnlySpan<Byte>, Half)

Source:

Half.cs

Tries to convert a UTF-8 character span containing the string representation of a number to its half-precision floating-point number equivalent.

public:
 static bool TryParse(ReadOnlySpan<System::Byte> utf8Text, [Runtime::InteropServices::Out] Half % result);

public static bool TryParse (ReadOnlySpan<byte> utf8Text, out Half result);

static member TryParse : ReadOnlySpan<byte> * Half -> bool

Public Shared Function TryParse (utf8Text As ReadOnlySpan(Of Byte), ByRef result As Half) As Boolean

Parameters

utf8Text

ReadOnlySpan<Byte>

A read-only UTF-8 character span that contains the number to convert.

result

Half

When this method returns, contains a half-precision floating-point number equivalent of the numeric value or symbol contained in utf8Text if the conversion succeeded or zero if the conversion failed. The conversion fails if the utf8Text is Empty or is not in a valid format. This parameter is passed uninitialized; any value originally supplied in result will be overwritten.

Returns

Boolean

true if utf8Text was converted successfully; otherwise, false.

TryParse(ReadOnlySpan<Char>, Half)

Source:

Half.cs

Converts the span representation of a number to its half-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed.

public:
 static bool TryParse(ReadOnlySpan<char> s, [Runtime::InteropServices::Out] Half % result);

public static bool TryParse (ReadOnlySpan<char> s, out Half result);

static member TryParse : ReadOnlySpan<char> * Half -> bool

Public Shared Function TryParse (s As ReadOnlySpan(Of Char), ByRef result As Half) As Boolean

Parameters

s

ReadOnlySpan<Char>

A read-only span that contains a number to convert.

result

Half

When this method returns, contains the half-precision floating-point number equivalent to the numeric value or symbol contained in s, if the conversion succeeded, or a default Half value if the conversion failed. The conversion fails if the s parameter is null or Empty or is not a number in a valid format. If s is a valid number less than MinValue, result contains NegativeInfinity. If s is a valid number greater than MaxValue, result contains PositiveInfinity. This parameter is treated as uninitialized.

Returns

Boolean

true if s was converted successfully, false otherwise.

TryParse(String, Half)

Source:

Half.cs

Converts the string representation of a number to its half-precision floating-point number equivalent. A return value indicates whether the conversion succeeded or failed.

public:
 static bool TryParse(System::String ^ s, [Runtime::InteropServices::Out] Half % result);

public static bool TryParse (string? s, out Half result);

static member TryParse : string * Half -> bool

Public Shared Function TryParse (s As String, ByRef result As Half) As Boolean

Parameters

s

String

A string that contains a number to convert.

result

Half

When this method returns, contains the half-precision floating-point number equivalent to the numeric value or symbol contained in s, if the conversion succeeded, or a default Half value if the conversion failed. The conversion fails if s is null or Empty or is not a number in a valid format. If s is a valid number less than MinValue, result contains NegativeInfinity. If s is a valid number greater than MaxValue, result contains PositiveInfinity. This parameter is treated as uninitialized.

Returns

Boolean

true if the conversion was successful; otherwise, false.
