A flonum represents a floating point number. The translation is
indirect: a decimal floating point number from the text is converted by
as to a generic binary floating point number of more than
sufficient precision. This generic floating point number is converted
to a particular computer’s floating point format (or formats) by a
as specialized to that computer.
A flonum is written by writing (in order)
asthe rest of the number is a flonum. e is recommended. Case is not important.
On the H8/300, Renesas / SuperH SH, and AMD 29K architectures, the letter must be one of the letters ‘DFPRSX’ (in upper or lower case).
On the ARC, the letter must be one of the letters ‘DFRS’ (in upper or lower case).
On the Intel 960 architecture, the letter must be one of the letters ‘DFT’ (in upper or lower case).
On the HPPA architecture, the letter must be ‘E’ (upper case only).
At least one of the integer part or the fractional part must be present. The floating point number has the usual base-10 value.
as does all processing using integers. Flonums are computed
independently of any floating point hardware in the computer running
