NAG Toolbox: nag_machine_real_largest (x02al)

Purpose

nag_machine_real_largest (x02al) returns the largest positive floating point number.

Syntax

[result] = x02al
[result] = nag_machine_real_largest

Description

nag_machine_real_largest (x02al) returns the largest positive number in the model of floating point arithmetic described in the X02 Chapter Introduction. The returned value is equal to (1bp) × bemax ( 1- b-p ) × bemax , where bb is the arithmetic base (see nag_machine_model_base (x02bh)) and emax emax  is the maximum exponent (see nag_machine_model_maxexp (x02bl)) in the model.
