83Plus:BCALLs:4264

Synopsis

Official Name: FDiv10

BCALL Address: 4264

Performs a fast divide by 10 on op1.

Inputs

• OP1 = floating point number

Outputs

• OP1 = op1 / 10

Registers Destroyed

• A

Comments

This function divides op1 by 10. This is done by decrementing the exponent. Checks are performed to prevent an underflow. This is much faster than FPDiv when op2=10.

Example

Suppose op1=00h,80h,10h,00h,... After B_CALL FDiv10, op1=00h,7Fh,10h,00h,...
