xnear = nearfloat(dir, x)

Parameters

• dir : string ("succ" or "pred")
• x : real scalar, vector or matrix
• xnear : real scalar, vector or matrix

Description

This function computes, in the element wise meaning, the corresponding neighbours of the elements of x (in the underlying floating point set, see number_properties), the successors if dir = "succ" and the predecessors if dir = "pred"

Examples

format("e",22)
nearfloat("succ",1) - 1
1 - nearfloat("pred",1)
