Hexadecimal to double number conversion
Syntax
f = hex2num('hex_value')
Description
f = hex2num('hex_value')
converts hex_value 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.
