Storage Register Overflow
If the magnitude of a number in any of the eight storage registers
exceeds 9.999999999 x 109, the HP-25 display immediately
shows (overflow) to indicate that a storage register has
overflowed.
For example, if you use storage register arithmetic to attempt
to calculate the product of 1 x 10°°and 7.5 x 10°°in register R,,
the register overflows and the display shows@. To see the
result of storage register overflow:
