hex2num (MATLAB Functions)

Convert hexadecimal number string to double-precision number

Syntax

```
n = hex2num(S)
```

Description

n = hex2num(S), where S is a 16 character string representing a hexadecimal number, returns the IEEE double-precision floating-point number n that it represents. Fewer than 16 characters are padded on the right with zeros. If S is a character array, each row is interpreted as a double-precision number.

NaNs, infinities and denorms are handled correctly.

Example

```
hex2num('400921fb54442d18') 
```

returns Pi.

```
hex2num('bff') 
```

returns

```
ans =

    -1
```
