6.11.3 Operational data
(1) Four fundamental operations (+, -, *, /, MOD)
The data type combinations and conversion methods for four fundamental
operations (+, -, *, /, MOD) are shown below.
Operation result = [Data 1] operator [Data 2]
Operator indicates +, -, *, / or MOD
Internal operation is performed after conversion into the type of the operation
result. If there is no operation result such as a conditional expression, internal
operation is performed with 32-bit data. For MOD, however, if the operation result
type is 64-bit data with floating point, internal operation is performed with 32-bit
data, which is then converted into the operation result type and stored.
