(1) Converts the 64-bit floating-point real number specified for to 32-bit BIN data, and stores
the result to .
(2) 64-bit floating-point real numbers between 2147483648.0 and 2147483647.0 can be
specified for + 3, + 2, + 1 or .
(3) The integer value stored in + 1 and is stored as BIN 32 bits.
(4) After conversion, the first digit from the decimal point of the 64-bit floating-point real number
is rounded off.
