List of clearBit() Examples

Examples of clearBit()

java.math.BigInteger.clearBit()
Returns a BigInteger whose value is equivalent to this BigInteger with the designated bit cleared. (Computes {@code (this & ~(1<
org.apache.directory.api.asn1.util.BitString.clearBit()
Clear a bit at a specified position. The bits are stored from left to right. For instance, if we have 10 bits, then they are coded as b0 b1 b2 b3 b4 b5 b6 b7 - b8 b9 x x x x x x @param pos The bit to clear
