The other main source of slowness in Atari BASIC was the floating point (FP) routines. [TURBO-BASIC XL] replaced these for a great improvement in performance. Altirra BASIC does not, it calls whatever FP routines are found in the machine's ROMs. However, the Altirra emulator contains a second set of FP ROMs that can be optionally turned on, addressing this issue. This FP package, unlike TURBOs, remains fully compatible with Atari's original version and is suitable for burning to ROM. Because it does not include its own FP library, Altirra has more free memory on startup.
