def fromString(s: String): Option[Int64]SourceParse the string s as an Int64, leading or trailing whitespace is trimmed.
A successful parse is wrapped with Some(x), a parse failure is indicated by None.

of the highest-order/leftmost one-bit in x.
Returns 0 if x=0.
def highestOneBitPosition(x: Int64): Int32SourceReturns the position of the highest-order/leftmost one-bit in x.
Possible return values: 0 (rightmost bit) - 63 (leftmost bit)
-1 if x = 0

If the given value is 0 or negative, 0 is returned.
def logicalRightShift(dist: { dist = Int32 }, x: Int64): Int64SourceReturns the logical right shift of x by distance.
Only the rightmost 6 bits of distance are considered (ie. distance rem 64).
A zero is shifted into the leftmost position regardless of sign extension.
def lowestOneBit(x: Int64): Int64SourceReturns a value with at most a single one-bit, in the position
of the highest-order/leftmost one-bit in x.
Returns 0 if x=0.
def lowestOneBitPosition(x: Int64): Int32SourceReturns the position of the lowest-order/rightmost one-bit in x.
Possible return values: 0 (rightmost bit) - 63 (leftmost bit)
-1 if x = 0
def mod(x: Int64, n: Int64): Int64SourceReturns the Euclidean modulo of x and n.
The result is always non-negative.
def numberOfLeadingZeros(x: Int64): Int32SourceReturns the number of zero bits preceding the
highest-order/leftmost one-bit in x.
Returns 64 if x=0.
def numberOfTrailingZeros(x: Int64): Int32SourceReturns the number of zero bits following the
lowest-order/rightmost one-bit in x.
Returns 64 if x=0.
def parse(radix: Int32, s: String): Result[String, Int64]SourceParse the string s as an Int64, where the radix is used while parsing.
Leading or trailing whitespace is trimmed.
A successful parse is wrapped with Ok(x), a parse failure is indicated by Err(_).
def rem(x: Int64, n: Int64): Int64SourceReturns the remainder of x / n.
The result can be negative.

def reverse(x: Int64): Int64SourceReturns the value obtained by reversing the bits in the
two's complement binary representation of x.
def rotateLeft(dist: { dist = Int32 }, x: Int64): Int64SourceReturns the the value obtained by rotating the two's complement
binary representation of x left by distance bits.
def rotateRight(dist: { dist = Int32 }, x: Int64): Int64SourceReturns the the value obtained by rotating the two's complement
binary representation of x right by distance bits.
def setBit(pos: { pos = Int32 }, x: Int64): Int64SourceReturns x with the bit at position position set (to 1).
