Method Detail

gcd

@Deprecated
public static int gcd(int aValue1,
                                 int aValue2)

Deprecated. Since Version 22. Use RationalNumber.gcd(int,int) instead

Greatest Common Denominator

gcd

@Deprecated
public static long gcd(long aValue1,
                                  long aValue2)

Deprecated. Since Version 22. Use RationalNumber.gcd(long,long) instead

getError

@Deprecated
public static double getError(int aScale)

Deprecated. Since Version 22. Use NumberContext.getError() instead.

The (rounding) error is half the size of a one in the last decimal place. If the scale is set to 3 then the error is 0.0005.

Returns:

The rounding error size

isZero

@Deprecated
public static boolean isZero(double aNmbr)

Deprecated. Since Version 22. Use TypeUtils.isZero(double) instead

isZero

@Deprecated
public static boolean isZero(Number aNmbr)

Deprecated. Since Version 22. Use TypeUtils.isZero(double) instead

max

@Deprecated
public static int max(int anIntA,
                                 int anIntB,
                                 int anIntC)

Deprecated. Since Version 22. Use MatrixUtils.max(int,int,int) instead

min

@Deprecated
public static int min(int anIntA,
                                 int anIntB,
                                 int anIntC)

Deprecated. Since Version 22. Use MatrixUtils.min(int,int,int) instead

power10

@Deprecated
public static long power10(int anExponent)

Deprecated. Since Version 22. Use something else...

PrimitiveFunction.POW, PrimitiveFunction.POWER, BigFunction.POW, BigFunction.POWER

randomInteger

@Deprecated
public static int randomInteger(int aLower,
                                           int aHigher)

Deprecated. Since Version 22. Use Uniform.randomInteger(int,int) instead

Returns:

An integer: aLower <= ? < aHigher

toBigDecimal

@Deprecated
public static BigDecimal toBigDecimal(Number aNumber)

Deprecated. Since Version 22. Use TypeUtils.toBigDecimal(Number) instead

If the input Number is a BigDecimal it is passed through unaltered. Otherwise an equivalent BigDecimal is created.

Parameters:

aNumber - Any Number

Returns:

A corresponding BigDecimal

toComplexNumber

@Deprecated
public static ComplexNumber toComplexNumber(Number aNumber)

Deprecated. Since Version 22. Use TypeUtils.toComplexNumber(Number) instead

toRationalScalar

@Deprecated
public static RationalNumber toRationalScalar(Number aNumber)

Deprecated. Since Version 22. Use TypeUtils.toRationalNumber(Number) instead
