default

◆ vnl_decnum() [4/10]

vnl_decnum::vnl_decnum ( std::string const & r )

Constructor from string.

This is the principal constructor for vnl_decnum; it essentially parses the input into (in that order) the sign, the mantissa, and the exponent, which turn out (surprise!) to be the three data members of this class. Parsing stops at the first unexpected character, so in the worst case no characters can be used and the decnum is zero.

◆ vnl_decnum() [7/10]

vnl_decnum::vnl_decnum ( long r )

inlineexplicit

Creates a vnl_decnum from a long integer.

Uses the "unsigned long" constructor and additionally sets the sign

Definition at line 117 of file vnl_decnum.h.

◆ vnl_decnum() [8/10]

vnl_decnum::vnl_decnum ( unsigned int r )

Creates a vnl_decnum from an unsigned integer.

Uses the "unsigned long" constructor.

Definition at line 127 of file vnl_decnum.h.

◆ vnl_decnum() [10/10]

vnl_decnum::vnl_decnum ( double r )

Definition at line 358 of file vnl_decnum.h.

◆ comp()

bool vnl_decnum::comp	(	std::string const &	a,
		std::string const &	b
	)

staticprivate

This is "operator<" for strings.

The arguments should consist of digits only (interpreted as mantissas with the same exponent). The shorter of the two arguments is implicitly zero-padded.

Definition at line 146 of file vnl_decnum.cxx.

◆ compactify()

vnl_decnum & vnl_decnum::compactify ( )

Remove all trailing zeros from the mantissa, and increase the exponent accordingly.

Return the (thus modified) *this. This effectively compactifies the data representation of *this, and meanwhile increases the exponent. No other methods have this effect; to the contrary: e.g. operator+(1) often decreases the exponent to 0.

Definition at line 441 of file vnl_decnum.cxx.

◆ data()

std::string vnl_decnum::data ( ) const

inline

Definition at line 98 of file vnl_decnum.h.

◆ div()

std::string vnl_decnum::div	(	std::string const &	a,
		std::string &	b
	)

staticprivate

Returns the largest one-significant-digit divisor of the two arguments.

The largest multiple of the second argument not larger than the first one is returned in the second argument. (I.e.: the product of the original second argument with the returned divisor.) The arguments should consist of digits only and the first one should be numerically larger than the second one.

Definition at line 321 of file vnl_decnum.cxx.

◆ exp()

long vnl_decnum::exp ( ) const

inline

Definition at line 100 of file vnl_decnum.h.

◆ expand()

vnl_decnum& vnl_decnum::expand ( )

inline

Expand integers to their non-compactified representation, i.e., without "e" notation.

Other operators (like + or -) might implicitly have this effect, as the implementation here indeed suggests.

◆ minus()

vnl_decnum vnl_decnum::minus	(	std::string const &	a,
		std::string const &	b,
		long	exp
	)

staticprivate

Returns the difference of the two first arguments (interpreted as mantissas with the same exponent).

Both arguments should consist of digits only and the first one should be numerically larger than the second one. The third argument will be used as the exponent of the result.

Definition at line 217 of file vnl_decnum.cxx.

◆ mult()

std::string vnl_decnum::mult	(	std::string const &	a,
		char	b
	)

staticprivate

Returns the product of the two arguments.

The first argument should consist of digits only; the second argument should be a single digit.
