Class FloatingPointType
The C/C++ floating point types. See 4.5. This includes float
, double
and long double
, the
fixed-size floating-point types like _Float32
, the extended-precision floating-point types like
_Float64x
, and the decimal floating-point types like _Decimal32
. It also includes the complex
and imaginary versions of all of these types.

Predicates
getBase | Gets the numeric base of this type’s representation: 2 (binary) or 10 (decimal). |
getDomain | Gets the type domain of this type. Can be |
getRealType | Gets the corresponding real type of this type. For example, the corresponding real type of |
isExtendedPrecision | Holds if this type is an extended precision floating-point type, such as |
Inherited predicates
explain | Gets a detailed string representation explaining the AST of this type (with all specifiers and nested constructs such as pointers). This is intended to help debug queries and is a very expensive operation; not to be used in production queries. | from BuiltInType |
findRootCause | Gets the source of this element: either itself or a macro that expanded to this element. | from Element |
fromSource | Holds if this element may be from source. This predicate holds for all elements, except for those in the dummy file, whose name is the empty string. The dummy file contains declarations that are built directly into the compiler. | from Element |
getAPrimaryQlClass | Gets the name of a primary CodeQL class to which this element belongs. | from ArithmeticType |
getASpecifier | Gets a specifier of this type, recursively looking through | from Type |
getATypeNameUse | Gets as many places as possible where this type is used by name in the source after macros have been replaced (in particular, therefore, this will find type name uses caused by macros). Note that all type name uses within instantiations are currently excluded - this is too draconian in the absence of indexing prototype instantiations of functions, and is likely to improve in the future. At present, the method takes the conservative approach of giving valid type name uses, but not necessarily all type name uses. | from Type |
getAlignment | Gets the alignment of this type in bytes. | from Type |
getAnAttribute | Gets an attribute of this type. | from Type |
getEnclosingElement | Gets the closest | from Element |
getFile | Gets the primary file where this element occurs. | from Element |
getLocation | Gets the primary location of this element. | from Type |
getName | Gets the name of this type. | from BuiltInType |
getParentScope | Gets the parent scope of this | from Element |
getPointerIndirectionLevel | Gets the pointer indirection level of this type. | from Type |
getPrimaryQlClasses | Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs. | from ElementBase |
getSize | Gets the size of this type in bytes. | from Type |
getUnderlyingType | Gets this type after typedefs have been resolved. | from Type |
getUnspecifiedType | Gets this type after specifiers have been deeply stripped and typedefs have been resolved. | from Type |
hasName | Holds if this type is called | from Type |
hasSpecifier | Holds if this declaration has a specifier called | from Type |
internal_getAnAdditionalSpecifier | Internal – should be | from Type |
involvesReference | Holds if this type involves a reference. | from Type |
involvesTemplateParameter | Holds if this type involves a template parameter. | from Type |
isAffectedByMacro | Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of | from Element |
isConst | Holds if this type is const. | from Type |
isDeeplyConst | Holds if this type is constant and only contains constant types. For instance, a | from Type |
isDeeplyConstBelow | Holds if this type is constant and only contains constant types, excluding the type itself. It is implied by Type.isDeeplyConst() and is just used to implement that predicate. For example, | from BuiltInType |
isFromTemplateInstantiation | Holds if this | from Element |
isFromUninstantiatedTemplate | Holds if this | from Element |
isInMacroExpansion | Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see | from Element |
isVolatile | Holds if this type is volatile. | from Type |
refersTo | Holds if this type refers to type | from Type |
refersToDirectly | Holds if this type refers to type | from Type |
resolveTypedefs | Gets this type with any typedefs resolved. For example, given | from Type |
stripTopLevelSpecifiers | Gets this type after any top-level specifiers and typedefs have been stripped. | from Type |
stripType | Gets the type stripped of pointers, references and cv-qualifiers, and resolving typedefs. For example, given | from Type |
toString | Gets a textual representation of this element. | from BuiltInType |
