Synopsis

Official Name: IncO1Exp

BCALL Address: 426A

Increments OP1's exponent.

Inputs

  • OP1 = floating point number

Outputs

  • OP1 's exponent incremented

Registers Destroyed

  • A

Comments

This function increments the exponent of OP1. Checks are not performed to prevent an overflow.

Example

Suppose OP1=00h,80h,10h,00h,...
After B_CALL IncO1Exp, OP1=00h,81h,10h,00h,...


Suppose OP1=00h,FFh,10h,00h,...
After B_CALL IncO1Exp, OP1=00h,00h,10h,00h,...
