BCD to Real with Implied Decimal Point (BCDTOR) (IB-560)
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).
For example, BCDTOR K1234 with an implied number of decimal points equal to K1, would
yield R123.4
BCDTOR Parameters
• Value (WORD BCD): specifies the word
or constant that will be converted to a Real
number
• Number of Decimal Points: specifies the
number of implied decimal points in the
Result DWORD
• Result (DWORD REAL): specifies the
location where the Real number will be placed
BCDTOR Example
In the following example, the BCDTOR instruction is used to convert the 16-bit data in
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.
K2 in the Number of Decimal Points implies the data will have two digits to the right of the
decimal point.
