WebOct 2, 2024 · As x 2 = 10 − 20 is zero relative to 1 in floating point precision, exp ( x) is 1 + x rounded to floating point precision (or 1 ulp larger - unit-in-the-last-place). exp ( x) − 1 returns thus a truncated version of x, essentially its leading 5 or 6 digits. Consequently ( exp ( x) − 1) − x will return the remainder of x to this truncation. WebExpressing floating point numbers in IEEE...
