Synopsis
Official Name: DivHLbyE
BCALL Address: 8048
Divides register HL by register E and stores the result in DE and the remainder in HL.
Inputs
- HL = numerator
- E = denominator
Outputs
- DE = HL / E
- HL = HL % E
Destroys
- a, IX, HL, DE
- Contents of memory addresses 8251h - 8253h
Comments
Simple enough to implement yourself if speed is important.
Example
ld hl,103h ld e,3 B_CALL DivHLbyE ;should return DE=56h and HL=1
