IEEE Standard 754 for Binary Floating-Point Arithmetic
IEEE 754 specifies three types or Formats of floating-point numbers: Single ( Fortran's REAL*4, C's float ), ( Obligatory ), Double ( Fortran's REAL*8, C's double ), ( Ubiquitous ), and Double-Extended ( Fortran REAL*10+, C's long double ), ( Optional ). ( A fourth Quadruple-Precision format is not specified by IEEE 754 but has become a de ...

Paths in graphs - People
people.eecs.berkeley.edushows a path of length 3. This chapter is about algorithms for nding shortest paths in graphs. Path lengths allow us to talk quantitatively about the extent to which different vertices of a graph are separated from each other: The distance between two nodes is the length of the shortest path between them.
