5.12 Type Conversion Functions
The Conversion functions change a data item from one number format (data type) to another. Many
programming 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.
DEG_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.
