BCD to Real with Implied Decimal Point (BCDTOR) (IB-560)
1
BCD to Real with Implied Decimal Point converts the given 4-digit WORD BCD value to a
Real number, with the implied number of decimal points (K0-K4).
230
2
For example, BCDTOR K1234 with an
240
implied number of decimal points equal to
250-1 K1, would yield R123.4

BCDTOR Example
In the following example, the BCDTOR instruction is used to convert the 16-bit data in
10
V2000 from a 4-digit BCD data format to a 32-bit REAL (floating point) data format and
store into V3000 and V3001 when C100 turns on.
11
K2 in the Number of Decimal Points implies the data will have two digits to the right of the
decimal point.
