Chapter 5. Function Block Diagram (FBD)268 PACSystems* RX7i, RX3i and RSTi-EP CPU Programmer's Reference Manual GFK-2950C5.12 Type Conversion FunctionsThe Conversion functions change a data item from one number format (data type) to another. Manyprogramming instructions, such as math functions, must be used with data of one type. As a result,data conversion is often required before using those instructions.Function DescriptionConvert AnglesDEG_TO_RAD: Converts degrees to radians.RAD_TO_DEG: Converts radians to degrees.For details, refer to Conversion Functions in Chapter 4.Convert to BCD4 (4-digit Binary-Coded-Decimal)UINT_TO_BDC4: Converts UINT (16-bit unsigned integer) to BCD4.INT_TO_BCD4: Converts INT (16-bit signed integer) to BCD4.For details, refer to Conversion Functions in Chapter 4.Convert to BCD8 (8-digit Binary-Coded-Decimal )DINT_TO_BD8: Converts DINT (32-bit signed integer) to BCD8.For details, refer to Conversion Functions in Chapter 4.Convert to INT (16-bit signed integer)BCD4_TO_INT: Converts BCD to INT.UINT_TO_INT: Converts UINT to INTDINT_TO_INT: Converts DINT to INT..REAL_TO_INT: Converts REAL to INT.For details, refer to Conversion Functions in Chapter 4.Converts a 16-bit string (WORD) value to INT.For details, refer to Convert WORD to INT below.Convert to UINT (16-bit unsigned integer)BCD4_TO_UINT: Converts BCD4 to UINT.INT_TO_UINT: Converts INT to UINT.DINT_TO_UINT: Converts DINT to UINT.REAL_TO_UINT: Converts REAL to UINT.For details, refer to Conversion Functions in Chapter 4.WORD_TO_UINT: Converts a 16-bit string (WORD) value to UINT.For details, refer to Convert DWORD to DINT below.Convert to DINT (32-bit signed integer)BCD8_TO_DINT: Converts BCD8 to DINT.UINT_TO_DINT: Converts UINT to DINT.For details, refer to Conversion Functions in Chapter 4.
