eu.simuline.util.RealRepresentation

eu.simuline.util.RealRepresentation.BigDecimalRep

Enclosing class:

RealRepresentation

private static final class RealRepresentation.BigDecimalRep
extends RealRepresentation

Describes the representation of a BigDecimal-value. It is characterized by the RealRepresentation.mantissa() and the RealRepresentation.exponent. The mantissa in turn splits into the RealRepresentation.integer and the RealRepresentation.fractional part.

Field Detail

MAX_FRAC_DIGITS_NO_EXP

private static final int MAX_FRAC_DIGITS_NO_EXP

The number of digits right of the point such that the representation is without exponent. This evaluates to -3 as specified for double's in Double.toString(double) and is used by #RealRepresentation.BigDecimalRep(BigDecimal).

MAX_INT_DIGITS_NO_EXP

private static final int MAX_INT_DIGITS_NO_EXP

The number of digits left of the point such that the representation is without exponent. This evaluates to 7 as specified for double's in Double.toString(double) and is used by #RealRepresentation.BigDecimalRep(BigDecimal).

Constructor Detail

BigDecimalRep

BigDecimalRep(BigDecimal dec)

Constructs a newly allocated BigDecimalRep that represents given BigDecimal argument.

Parameters:

dec - the value to be represented by this BigDecimalRep.

BigDecimalRep

BigDecimalRep(String dStr)

Constructs a newly allocated BigDecimalRep object that represents the floating-point value of type double represented by the string. The string is converted to a double value as if by the method Double.valueOf(java.lang.String).

Parameters:

dStr - a string to be converted to a BigDecimalRep.
