I don't remember which binary floating point representation is default
in Fortran, but you should use the appropriate OTS$CVT_T_x function.
For example, if you are using IEEE S-floating binary values then you
would use OTS$CVT_T_S.

See the online or printed help for all the arguments and flags.  There
are options which may be useful in your particular application.

The return value from that routine will tell you if the conversion
failed, which would suggest a non-numeric value in the text string.
