TrailingZeros:Int32 value:Int32

Parameter	Mode	Type	Default	Description
value	In	Int32	required	An integer.

Returns: How many of the lowest bits are 0.

Description

〔BlitzLLVM〕 This command does not exist in the original Blitz products. BlitzLLVM adds it.

Counts the bits that are 0 after the last 1, from the lowest bit up. A number of 0 has all of its bits counted. This is a BlitzLLVM extension. It looks at the bits of the number the way its type has them, so the same value counts differently as a Byte, an Int or a Long: a number written in the program is an Int (32 bits) unless it is larger, and Byte, UByte, Short, UShort, UInt, Long and ULong give the other widths. A real or a text is taken as an Int, like the bit operators do.

Differences

• Not in the originals.
