Reads data encoded according to the IEEE standard for double precision floating-point numbers, such as data produced with the 8087 co-processor or 486 and higher CPU’s.
Float is the standard adopted for most microcomputer software, however it is not the one used by interpretive BASIC. Float stores the least significant byte of the significand (mantissa) first (left most) and the most significant byte rightmost. The length of the field type is 4 or 8 bytes.
