Type Aliases

Name	Description
`FloatType`	Alias for the floating-point type described by this specialization.
`UintType`	Alias for the size-equivalent unsigned integer type.

Static Member Functions

Name	Description
`adjustMantissaForHexDigits`	Adjust the specified `ieeeMantissa` bits for hexfloat conversion. This method is a no-op for `double` type.
`toFloatType`	Converts the bits of the specified size-equivalent unsigned integer `uIntValue` into the "original" floating point type.
`toUintType`	Converts the bits of the specified floating point `value` into the size-equivalent unsigned integer type.

Static Data Members

Name	Description
`k_DENORM_MANTISSA_MASK`	Mask for the fraction bits of a subnormal value (no leading bit).
`k_EXPONENT_BIAS`	Bias added to the true exponent in the encoded exponent field.
`k_EXPONENT_BITS`	Number of bits in the IEEE-754 exponent field.
`k_EXPONENT_MASK`	Mask for the unshifted exponent field bits.
`k_EXPONENT_SHIFT`	Bit offset of the exponent field within the integer representation.
`k_GENERAL_MAX_OUTPUT_LENGTH`	Maximum required buffer size for `std::to_chars_format::general` with the maximum precision.
`k_MANTISSA_BITS`	Number of significand bits including the implicit leading bit.
`k_MANTISSA_HEX_DIGITS`	The hex digits needed to represent the mantissa in a hexfloat.

`k_MIN_BINARY_EXPONENT`	Minimum unbiased binary exponent for a finite normal value.
`k_MIN_VALUE`	Smallest positive normalized `double` value (`DBL_MIN`).
`k_NORMAL_MANTISSA_MASK`	Mask for the significand of a normal value, including the leading bit.
`k_SHIFTED_EXPONENT_MASK`	Mask for the exponent field in its natural position in the representation.
`k_SHIFTED_SIGN_MASK`	Mask for the sign bit in its natural position in the representation.
`k_SIGN_SHIFT`	Bit offset of the sign bit within the integer representation.
`k_SPEC_NAN_MANTISSA_MASK`	Mask selecting the quiet-NaN indicator bit in the mantissa.
