FLT
T [ ] n ;
(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 23 to 30 : Exponent part
Bits 31 : Sign part
(3) The following values can be handled as floating-point type real numbers.
