### Field Detail

#### EXP_INT_A

    private static final double[] EXP_INT_A

Exponential evaluated at integer values, exp(x) = expIntTableA[x + EXP_INT_TABLE_MAX_INDEX] + expIntTableB[x+EXP_INT_TABLE_MAX_INDEX].

#### EXP_INT_B

    private static final double[] EXP_INT_B

Exponential evaluated at integer values, exp(x) = expIntTableA[x + EXP_INT_TABLE_MAX_INDEX] + expIntTableB[x+EXP_INT_TABLE_MAX_INDEX]

#### EXP_FRAC_A

    private static final double[] EXP_FRAC_A

Exponential over the range of 0 - 1 in increments of 2^-10 exp(x/1024) = expFracTableA[x] + expFracTableB[x]. 1024 = 2^10

#### EXP_FRAC_B

    private static final double[] EXP_FRAC_B

Exponential over the range of 0 - 1 in increments of 2^-10 exp(x/1024) = expFracTableA[x] + expFracTableB[x].

#### LN_MANT

    private static final double[][] LN_MANT

Extended precision logarithm table over the range 1 - 2 in increments of 2^-10.
