Constructor Detail

PolynomialExpression

public PolynomialExpression(java.lang.String expression,
                            int precision)

Parameters:

expression - A valid polynomial expression, having powers of the variable as only non-negative integers.

Method Detail

setPrecision

public void setPrecision(int precision)

Parameters:

precision - The precision to use. If set to any value other than 1 (DOUBLE_PRECISION) or 2 (BIGDECIMAL_PRECISION), it defaults to DOUBLE_PRECISION

getPrecision

public int getPrecision()

solve

public java.util.List<java.lang.String> solve(java.util.List<java.lang.String> list)

Description copied from class: MathExpression

used by the main parser solve to figure out SBP portions of a multi-bracketed expression (MBP)

Overrides:

solve in class MathExpression

Parameters:

list - a list of scanner tokens of a maths expression

Returns:

the solution to a SBP maths expression

doublePrecisionSolve

public java.util.List<java.lang.String> doublePrecisionSolve(java.util.List<java.lang.String> list)

Used by the main parser solve to figure out SBP portions of a multi-bracketed expression (MBP)

Parameters:

list - a list of scanner tokens of a maths expression

Returns:

the solution to a SBP maths expression. The precision returned here is that of double numbers, namely about 16d.p

bigDecimalPrecisionSolve

public java.util.List<java.lang.String> bigDecimalPrecisionSolve(java.util.List<java.lang.String> list)
