org.das2.datum.RationalNumber

represent a rational number

RationalNumber( double d )

create a rationalNumber that is very close to d.

RationalNumber( org.das2.datum.Ratio n, org.das2.datum.Ratio exp )

create a rationalNumber with n * 10^exp

RationalNumber( org.das2.datum.Ratio n )

create a rationalNumber with n * 10^exp

RationalNumber( int n )

create a rationalNumber with n * 10^exp

RationalNumber( int n, int d )

create a new rational number with numerator n and denominator d. The result will be n/d*10^0

divide

divide by the number.

Parameters

Returns:

doubleValue

return a close representation using double.

Returns:

isOne

return true if the number is 1.

Returns:

isZero

return true if the number is 0.

Returns:

multiply

multiply by the number

Parameters

Returns:

parse

parse the string to get the RationalNumber. This simply calls Double.parseDouble, but a future implementation could do a better job of this.

Parameters

Returns:

pow

Parameters

Returns:

sqrt

returns the sqrt of the number, e.g. 4 * 10^

Returns:

toString

Returns:
