Implementations§

source§

impl ControlRegister

source

pub fn alternative_half_precision_format(&self) -> bool

AHP: Use an alternative format for half-precision floats when converting to/from other formats. Otherwise, use the IEEE half-precision format.

source

pub fn default_nan(&self) -> bool

DN: Always use the default encoding for NaN results. Otherwise, use the encoding from an input operand.

source

pub fn flush_to_zero(&self) -> bool

FZ: When a result would be denormal, yield zero instead. Otherwise, use the IEEE 754 behavior.

source

pub fn rounding_mode(&self) -> RoundingMode

RMode: The IEEE 754 rounding mode in use.

source

pub fn flush_to_zero_half_precision(&self) -> bool

FZ16: Counterpart to flush_to_zero for half-precision calculations.

Requires FEAT_FP16.

source

pub fn trapped_exceptions(&self) -> Exceptions

For each type of floating-point exception, defines whether the error will be trapped. If false, the corresponding flag in StatusRegister::exceptions will be set instead.

source

pub fn set_alternative_half_precision_format(&mut self, value: bool)

AHP: Use an alternative format for half-precision floats when converting to/from other formats. Otherwise, use the IEEE half-precision format.

source

pub fn with_alternative_half_precision_format(&mut self, value: bool) -> Self

AHP: Use an alternative format for half-precision floats when converting to/from other formats. Otherwise, use the IEEE half-precision format.

source

pub fn set_default_nan(&mut self, value: bool)

DN: Always use the default encoding for NaN results. Otherwise, use the encoding from an input operand.

source

pub fn with_default_nan(&mut self, value: bool) -> Self

source

pub fn set_flush_to_zero(&mut self, value: bool)
