Method Detail

isSmall

default boolean isSmall(double comparedTo)

Parameters:

comparedTo - What to compare with

Returns:

true if this is small compared to the magnitude of the input reference value.

norm

double norm()

this == this.signum().multiply(this.norm())

Returns:

The norm

signum

T signum()

this == this.signum().multiply(this.norm())

Returns:

A unit "vector"
