[R] Converting IEEE Float in 16 char hex back to float

[xlr82sas]

Hi,

If I do the following

sprintf("%A",pi)
"0X1.921FB54442D18"

I have this 16 byte character string

hx<-"400921FB54442D18"

This is the exact hex16 representation of PI in
IEEE float that R uses in Intel 32bit(little endian) Windows
SAS uses the same representation. 11 bit exponent and 53 bit mantissa.

I want to do is recreate the float exactly from the 16 char hex

something like

MyPI<-readChar(hx,numeric(),16)

or in SAS

MyPI=input("400921FB54442D18",hex16.);
put MyPI=;

MYPI=3.1415926536

What I am trying to do is set up a lossless
transfer method from SAS to R
