Methods in detail¶
Complex_d ( in Complex_d other )
copy constructor
Construct a complex number with real value re
Complex_d ( in Float64 re, in Float64 im )
Construct a complex number with real value re and
imaginary value im
Construct a complex number with real value re
Complex_d ()
default constructor
Boolean Complex_d.almostEqual? ( in Complex_d that )
Boolean Complex_d.almostEqual? ( in Complex_d that, in Float64 precision )
Check if the value of the complex number is equal to that, within
the specified precision
Return the angle of the complex number from its real and imaginary components
Complex_d.appendDesc? ( io String string )
Append a String description of this complex number
to the io String string
clone method
Boolean Complex_d.equal? ( in Complex_d that )
Return the inverse of this complex number
Boolean Complex_d.isAlmostZero? ( in Float64 precision )
Check if the value of the complex number is close enough zero, within the specified precision
Boolean Complex_d.isAlmostZero? ()
Boolean Complex_d.isZero? ()
Check if the value is zero
Return the length of this complex number
Float64 Complex_d.lengthSquared? ()
Complex_d Complex_d.linearInterpolate? ( in Complex_d that, in Float64 t )
