WebJan 16, 2024 · If either (or both) of the operands are floating point values, the division operator performs floating point division. Floating point division returns a floating point value, and the fraction is kept. For example, 7.0 / 4 = 1.75, 7 / 4.0 = 1.75, and 7.0 / 4.0 = 1.75. As with all floating point arithmetic operations, rounding errors may occur. shares register

WebJan 10, 2014 · ARMv7-A - divide by zero always returns a zero result. ARMv7-R - the SCTLR.DZ bit controls whether you get a zero result or a Undefined Instruction exception when you attempt to divide by zero (the default is to return zero). ARMv7-M - the CCR.DIV_0_TRP bit controls whether an exception is generated.

In mathematics, division by zero is division where the divisor (denominator) is zero. Such a division can be formally expressed as , where a is the dividend (numerator). In ordinary arithmetic, the expression has no meaning, as there is no number that, when multiplied by 0, gives a (assuming ); thus, division by zero is undefined (a type of singularity). Since any number multiplied by zero is zero… WebDividing a floating-point value by zero doesn't throw an exception; it results in positive infinity, negative infinity, or not a number (NaN), according to the rules of IEEE 754 arithmetic. Because the following example uses floating-point division rather than integer division, the operation does not throw a DivideByZeroException exception.

WebOct 21, 2024 · Currently, I receive an error from ifort "forrtl: error (73): floating divide by zero", which is traced back to the dfeast_scsrgv call. I know that the matrices in the generalized eigenvalue problem may contain small values (i.e. values close to zero). So the sparse patterns might contain zero values. Could this be the cause of the error?
