Visual Fortran Run-Time Errors Page 11 of 48
FOR$IOS_VFEVALERR². The value of a variable format expression was not within the
range acceptable for its intended use; for example, a field width was less than or equal to
zero. A value of 1 was assumed, except for a P edit descriptor, for which a value of zero
was assumed.
70³
severe (70): Integer overflow
FOR$IOS_INTOVF. During an arithmetic operation, an integer value exceeded byte,
word, or longword range. The result of the operation was the correct low-order part.
See the Data Representation chapter in the Programmer’s Guide for ranges of the
various integer data types. Consider specifying a larger integer data size (modify source
program or, for an INTEGER declaration, possibly use the /integer_size:size option).
71³
severe (71): Integer divide by zero
FOR$IOS_INTDIV. During an integer arithmetic operation, an attempt was made to
divide by zero. The result of the operation was set to the dividend, which is equivalent
to division by 1.
72³
error (72): Floating overflow
FOR$IOS_FLTOVF. During an arithmetic operation, a floating-point value exceeded
the largest representable value for that data type. See the Data Representation chapter in
the Programmer’s Guide for ranges of the various data types.
73³
error (73): Floating divide by zero
FOR$IOS_FLTDIV. During a floating-point arithmetic operation, an attempt was made
to divide by zero.
74³
error (74): Floating underflow
FOR$IOS_FLTUND. During an arithmetic operation, a floating-point value became less
than the smallest finite value for that data type. Depending on the values of the /fpe:n
option, the underflowed result was either set to zero or allowed to gradually underflow.
See the Data Representation chapter in the Programmer’s Guide for ranges of the
various data types.
75³
error (75): Floating point exception
FOR$IOS_SIGFPE. A floating-point exception occurred. Possible causes include:
Division by zero
Overflow
An invalid operation, such as subtraction of infinite values, multiplication of zero
by infinity without signs), division of zero by zero or infinity by infinity
Conversion of floating-point to fixed-point format when an overflow prevents
conversion
