Synopsis

Official Name: DivHLByA

BCALL Address: 4012

Divides the value in HL by the value in A.

Inputs

  • HL: integer
  • A: integer

Outputs

  • HL = HL / A
  • A = HL mod A

Registers Destroyed

  • none

Comments

Simple enough to implement if speed is important. However, it may return invalid results if A is larger than 127 since the routine does not correctly handle overflows.

Example

ld hl,13
ld a,5
B_CALL DivHLByA  ;should return HL=2, A=3
