TryParse(ReadOnlySpan<Byte>, NumberStyles, IFormatProvider, Half)

Source:

Half.cs

Tries to parse a span of UTF-8 characters into a value.

public:
 static bool TryParse(ReadOnlySpan<System::Byte> utf8Text, System::Globalization::NumberStyles style, IFormatProvider ^ provider, [Runtime::InteropServices::Out] Half % result) = System::Numerics::INumberBase<Half>::TryParse;

public static bool TryParse (ReadOnlySpan<byte> utf8Text, System.Globalization.NumberStyles style, IFormatProvider? provider, out Half result);

static member TryParse : ReadOnlySpan<byte> * System.Globalization.NumberStyles * IFormatProvider * Half -> bool

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

Parameters

utf8Text

ReadOnlySpan<Byte>

The span of UTF-8 characters to parse.

style

NumberStyles

A bitwise combination of number styles that can be present in utf8Text.

provider

IFormatProvider

An object that provides culture-specific formatting information about utf8Text.

result

Half

On return, contains the result of successfully parsing utf8Text or an undefined value on failure.

Returns

Boolean

true if utf8Text was successfully parsed; 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.

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.
