WebHP Fortran expects numeric data to be in native little endian order, in which the least-significant, rightmost bit (bit 0) or byte has a lower address than the most-significant, leftmost bit (or byte). For More Information: On using nonnative big endian and VAX floating-point formats, see Chapter 9. On HP Fortran I/O, see Chapter 6.

Single-precision floating-point format (sometimes called FP32 or float32) is a computer number format, usually occupying 32 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 … WebFloating-Point Exceptions and Fortran Programs compiled by f77 automatically display a list of accrued floating-point exceptions on program termination.

WebThe Fortran standard doesn't specify what precisions and ranges of floating point numbers need be supported by a given compiler. All it says is that at least two different kinds of real numbers need be supported and that larger of them takes exactly twice the memory to represent a number as the other (smaller) kind.
