Get the absolute value for a given number

Returns:

equalsInt

boolean equalsInt(int i)

Is this number equal an integer number?

Parameters:

i -

Returns:

opposite

INumber opposite()

getIm

ISignedNumber getIm()

Returns the imaginary part of a complex number

Returns:

real part

getRe

ISignedNumber getRe()

Returns the real part of a complex number

Returns:

real part
