83Plus:BCALLs:4087

Synopsis

Official Name: LJRND

BCALL Address: 4087

Adjusts OP1 to normalized floating point form and rounds to the 14th digit.

Inputs

• OP1 = floating point, not necessarily normalized

Outputs

• OP1 = normalized floating point

Registers Destroyed

• A, C, HL

Comments

This shifts all digits in the mantissa of the floating point in OP1 leftward if there are any leading zeros in the mantissa. The exponent is adjusted appropriately after the shift.

Example

Suppose OP1=00h,80h,01h,23h,45h,55h,55,55h,55h,55h. 
After calling this BCALL, OP1=00h,7Fh,12h,34h,55h,55h,55h,55h,56h,00h
