Syntax





double CosDoubleValue(CosObj obj)

Gets the value of obj as a double-precision floating-point real number.

An exception is raised if the given object has the wrong Cos type.

Parameters

obj —

The object whose value is obtained. It must have type CosInteger or CosReal (CosFixed). The result is undefined if the real value is outside the range of floating-point numbers.

Returns

The numeric value of obj, represented as a floating-point number.

float CosFloatValue(CosObj obj)

Gets the value of obj as a single-precision floating-point real number.

An exception is raised if the given object has the wrong Cos type.

Parameters

obj —

The object whose value is obtained. It must have type CosInteger or CosReal (CosFixed). The result is undefined if the real value is outside the range of floating-point numbers.

Returns

The numeric value of obj, represented as a floating-point number.

Syntax





CosObj CosNewDouble(CosDoc dP, ASBool indirect, double value)

Creates a new real-number object from a double-precision floating-point number associated with the specified document.

Parameters

	`dP` —	The document in which the number is used.

	`indirect` —	If `true`, it creates the real-number object as an indirect object, and sets the document `dP` object's `PDDocNeedsSave` flag (see `PDDocFlags`). If `false`, it creates the number as a direct object.

	`value` —	The real number, represented as a double-precision floating-point number.

Returns

A Cos object of type CosReal (CosFixed).

Since

PI_COS_VERSION >= 0x00090000

Platform availability: Macintosh, Windows, UNIX

Syntax





CosObj CosNewDoubleEx(CosDoc dP, ASBool indirect, double value, ASUns8 numSigDigs)

Creates a new real-number object from a double-precision floating-point number associated with the specified document.

Parameters

	`dP` —	The document in which the number is used.

	`indirect` —	If `true`, it creates the real-number object as an indirect object, and sets the document `dP` object's `PDDocNeedsSave` flag (see `PDDocFlags`). If `false`, it creates the number as a direct object.

	`value` —	The real number, represented as a double-precision floating-point number.

	`numSigDigs` —	The maximum number of significant digits to use when this object is written to a file. Legal values are 6-13 for direct objects, 6-16 for indirect objects

Returns

Creates a new real-number object from a single-precision floating-point number associated with the specified document.

Parameters

	`dP` —	The document in which the number is used.

	`indirect` —	If `true`, it creates the real-number object as an indirect object, and sets the document `dP` object's `PDDocNeedsSave` flag (see `PDDocFlags`). If `false`, it creates the number as a direct object.

CosNumberIsWithinASFixedRange

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASBool CosNumberIsWithinASFixedRange(CosObj obj)

Tests whether the value of a Cos number is inside the range of ASFixed numbers, [-32768.0, +32768.0).

If so, the ASFixed value may be obtained by calling CosFixedValue().

If not, the floating-point value may be obtained by calling CosFloatValue().

It raises an exception if obj is not a number (CosInteger or CosReal).

Parameters

obj —

A Cos integer or real number.

Returns

true if the value of the number is in the range of ASFixed, false otherwise.

CosNumberIsWithinASInt32Range

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASBool CosNumberIsWithinASInt32Range(CosObj obj)

Tests whether the value of a Cos number is inside the range of 32-bit integers, [-2147483648, +2147483647].

If so, the 32-bit value may be obtained by calling CosIntegerValue().

If not, the 64-bit value may be obtained by calling CosIntegerValue64().

It raises an exception if obj is not a number (CosInteger or CosReal).

Parameters

obj —

A Cos integer or real number.

Returns
