| constexpr TypeSize | getWithIncrement (ScalarTy RHS) const |
Add RHS to the underlying quantity. | |
| constexpr ScalarTy | getKnownMinValue () const |
| Returns the minimum value this quantity can represent. | |
| constexpr bool | isScalable () const |
| Returns whether the quantity is scaled by a runtime quantity (vscale). | |
| constexpr bool | isFixed () const |
| Returns true if the quantity is not scaled by vscale. | |
| constexpr bool | isKnownEven () const |
| A return value of true indicates we know at compile time that the number of elements (vscale * Min) is definitely even. | |
| constexpr bool | isKnownMultipleOf (ScalarTy RHS) const |
| This function tells the caller whether the element count is known at compile time to be a multiple of the scalar value RHS. | |
| constexpr bool | isKnownMultipleOf (const FixedOrScalableQuantity &RHS) const |
| Returns whether or not the callee is known to be a multiple of RHS. | |
| constexpr ScalarTy | getFixedValue () const |
| constexpr TypeSize | divideCoefficientBy (ScalarTy RHS) const |
| We do not provide the '/' operator here because division for polynomial types does not work in the same way as for normal integer types. | |

| constexpr TypeSize | coefficientNextPowerOf2 () const |
| constexpr bool | hasKnownScalarFactor (const FixedOrScalableQuantity &RHS) const |
| Returns true if there exists a value X where RHS.multiplyCoefficientBy(X) will result in a value whose quantity matches our own. | |
| constexpr ScalarTy | getKnownScalarFactor (const FixedOrScalableQuantity &RHS) const |
| Returns a value X where RHS.multiplyCoefficientBy(X) will result in a value whose quantity matches our own. | |
| void | print (raw_ostream &OS) const |
| Printing function. | |
