A
Numerical value range for each output type
This section describes the numerical value ranges that can be output for each output type.
■Integer type
The following table lists the numerical value ranges that can be expressed for each integer type.
■Real number type
The following table lists the numerical value ranges that can be expressed for each real number type.
When the value of the data exceeds the numerical value range, the following rule is applied to the output.
• When the value exceeds the upper limit of the positive value, +Inf is output.
• When the value falls below the lower limit of the negative value, -Inf is output.
• When the value is between the upper limit of the negative value and the lower limit of the positive value, 0 is output.
