bit_set

bit_set sets the bit position nBit of m to 0 (off) or 1 (on).

m = bit_set(m, nBit)
m = bit_set(m, nBit, cast)
m = bit_set(m, nBit, bool, cast)

Return Value

m is an integer matrix.

Parameters

m

m is an integer matrix.

nBit

nBit is the bit position starting with 0. For 32-Bit values all bits can be used (0..31). For 64 bit values only the bits 0 to 52 can be used.

cast

cast is one of the following values:

CAST_INT8 (0)  
CAST_UINT8 (1)  
CAST_INT16 (2)  
CAST_UINT16 (3)  
CAST_INT32 (4)  
CAST_UINT32 (5)  
CAST_INT64 (6)  
CAST_UINT64 (7) default value.

Comment

UniScript uses double precision floating-point values. When casted to a CAST_INT64 or CAST_UINT64 only the lower 53 Bits (Bit 0 .. Bit 52) can be used.

Example

m = 0;
m = bit_set(m, 40)

m = bit_set(m, 31, CAST_UINT32)

// bit 31 wieder löschen
m = bit_set(m, 31, 0, CAST_UINT32)
