[Explanation]
(1) A 32-bit integer (BIN value) including four decimal places is converted into a
floating-point type real number.
(2) A floating-point type real number is processed as single precision (32-bit) in the
binary floating-point format of the IEEE Standard.
Sign part ...................... 1 bit
Exponent part .............. 8 bits
Significant digit part...... 23 bits
Bits 0 to 22 : Significant digit part
31 22 15 Bit 0
Bits 31 : Sign part
Bits 23 to 30 : Exponent part
(3) The following values can be handled as floating-point type real numbers.

[Program Example]
#2002 : L = 10000 ;
#2004 : L = FLT [#2002 : L] ; #2004 : L = (461C4000)
16
(D2004, D2005 = (461C4000) 16)
#2006 : L = INT [#2004 : L] ; #2006 : L = 10000
