Real to Binary Conversion (RTOB)
The Real-to-Binary instruction converts the real number in
the accumulator to a binary value. The result resides in the
accumulator. Both the binary and the real number may use all
32 bits of the accumulator.
NOTE
1
: The decimal portion of the result will be rounded down (14.1 to 14 or - 14.1 to -15).
NOTE
2
: If the real number is negative, it becomes a signed decimal value.
In the following example, when X1 is on, the value in V1400 and V1401 is loaded into the
accumulator using the Load Double instruction. The RTOB instruction converts the real
value in the accumulator the equivalent binary number format. The value in the accumulator
is copied to V1500 and V1501 using the Out Double instruction. The Handheld Programmer
would display the binary value in V1500 and V1501 as a HEX value.
