Web3 Answers. Sorted by: 7. Floating point numbers are represented as a sum of binary fractions times a power of two. In single-precision IEEE-754 floating point numbers, the fractions range from 1 / 2 0 to 1 / 2 23 and the powers of two range from 2 − 126 to 2 127. For example: 12 = ( 1 1 + 1 2) ⋅ 2 3 = 1.5 ⋅ 8 = 12. Web27 de jan. de 2010 · Long counts up from 1 to 2^ (4*8). Float uses only 23 of the 32 bits for the "counting".

WebWith floating-point representation, the placement of the decimal point can ‘float’ relative to the significant digits of the number. For example, a fixed-point representation with a uniform decimal point placement convention can represent the numbers 123.45, 1234.56, 12345.67, etc, whereas a floating-point representation could in addition represent 1.234567, … WebHá 1 dia · 15.
