Uint16
Conversion functions uint16
- uint16 is a 16 bits (2 bytes) unsigned integer value type.
- uint16() is a function converting data items or units of other value types to the uint16 value type.
This page describes the uint16() function.
- uint16(a)
- literal w
uint16(a) results in a 16 bits(2 bytes) unsigned integer item converted from item a. The function results for:
- integer data items: the integer value is interpreted as uint16 value, if the value exceeds the allowed value range for the uint16 value type, the resulting value will be null;
- float32/64 data items: the value before the decimal point (so 1.9 will be rounded off to 1 and 2.0 to 2). If the value exceeds the allowed value range for the uint16 value type, the resulting value will be null;
- boolean data items : 1 for True values and 0 for False values;
- string data items, if the value starts with an allowed numeric value for the value type, this value is converted to a uint16 value type. Other characters after the numeric values are ignored. If the string does not start with an allowed numeric value for the value type, the resulting value will be null;
- units, a 16 bits(2 bytes) unsigned integer unit of the converted unit.
- data item or unit with Numeric, uint2, uint4, bool or string value type
- 5.15
- w suffix: since 7.105
