NUM2HEX Convert Numbers to IEEE Hex Strings

Section: Elementary Functions

Usage

Converts single and double precision arrays to IEEE hex strings. The syntax for its use is 
   y = num2hex(x)

where x is either a float or double array. The output y is a n-by-p character array, where n is the number of elements in x, and p is 16 for double arrays, and 8 for single arrays.

Example

Some interesting numbers 
--> num2hex([1 0 0.1 -pi inf nan])

ans = 
3ff0000000000000
0000000000000000
3fb999999999999a
c00921fb54442d18
7ff0000000000000
fff8000000000000

The same in single precision 

--> num2hex(float([1 0 0.1 -pi inf nan]))

ans = 
3f800000
00000000
3dcccccd
c0490fdb
7f800000
fff80000
