Constructors

this this(bool value): Constructs a decimal number from a boolean value. false == 0, true == 1
this this(string str): Undocumented in source.
this this(U r): Undocumented in source.
this this(U coefficient): Undocumented in source.
this this(U coefficient): Undocumented in source.
this this(D that): Undocumented in source.
this this(U coefficient, int exponent): Constructs a number from a boolean sign, an integer coefficient and an optional integer exponent. The sign of the number is the value of the sign parameter regardless of the sign of the coefficient. The intial precision of the number is deduced from the number of decimal digits in the coefficient.
this this(U coefficient, int exponent, bool sign): Undocumented in source.
