Public 成员函数
Constructors.
The bits of an integral type passed to the constructor will be interpreted as as fixed-point value. A floating-point type passed to the constructor will be converted to a fixed-point value.
	FixedPoint (typename detail::IntegerOfSizeAndSignedness< 8, SIGNED >::type x)
	FixedPoint (typename detail::IntegerOfSizeAndSignedness< 16, SIGNED >::type x)
	FixedPoint (typename detail::IntegerOfSizeAndSignedness< 32, SIGNED >::type x)
	FixedPoint (double x)
	FixedPoint (float x)

详细描述

template<int INTEGER_BITS, int FRACTIONAL_BITS, bool SIGNED = true>
class vrpn::FixedPoint< INTEGER_BITS, FRACTIONAL_BITS, SIGNED >

A fixed-point value class. All values are signed, two's-complement, by default.

模板参数

INTEGER_BITS	The number of bits devoted to the integer part.
FRACTIONAL_BITS	The number of bits devoted to the fractional part.

成员类型定义说明

IntegerType

template<int INTEGER_BITS, int FRACTIONAL_BITS, bool SIGNED = true>

typedef detail::IntegerOfSizeAndSignedness<INTEGER_BITS,SIGNED>::type IntegerType

Find an integer type large enough to hold INTEGER_BITS.

待办事项

add operators, lots and lots of operators?

Returns a floating-point representation of this fixed-point value.
