Found the power calculation evaluation seems to be wrong... I am still on Build 350, on a Raspberry Pi-4B. (Don't know if 351 has same problem) LB code: PRINT USING("###.#############", 6^1.5) (Identical to (6 * SQRT(6)). I-Phone calculator gives: 14.69693845669907, as does LB 4.5.1 I get the following result on LB4, LB5 build 351 on both Windows and on the Pi. 14.6969384566991 This is wrong? |

PRINT USING("###.#############", 6^1.5)
PRINT USING("###.#############", 6.0^1.5)
On Win10 Build 351 32bit I find that ^ maths function gives two answers 6^1.5 is wrong, 6.0^1.5 is correct
14.6969384566991 is the correct answer
Output I see
