# hex2num

## Purpose

Hexadecimal to double number conversion.

## Synopsis

    f = hex2num('string')

## Description

`hex2num('string')` converts the hex value in string `string` to the IEEE double precision floating-point number it represents. `NaN`, `Inf`, and denormalized numbers are all handled correctly. Fewer than 16 characters are padded on the right with zeros.

## Examples

    f =hex2num('400921fb54442d18')

    f =
        3.14159265358979

## Limitations

`hex2num` only works for IEEE numbers; it does not work for the floating-point representation of the VAX or other non-IEEE computers.
