Methods

abs(
) → Int64 
Returns the absolute value of this integer.
override

clamp(
dynamic lowerLimit, dynamic upperLimit) → Int64 
Clamps this integer to be in the range
lowerLimit
upperLimit
.override 
compareTo(
dynamic other) → int 
Compares this object to another object.
override

noSuchMethod(
Invocation invocation) → dynamic 
Invoked when a nonexistent method or property is accessed.
inherited

numberOfLeadingZeros(
) → int 
Returns the number of leading zeros in this Int64 as an int
between 0 and 64.
override

numberOfTrailingZeros(
) → int 
Returns the number of trailing zeros in this Int64 as an int
between 0 and 64.
override

remainder(
dynamic other) → Int64 
Returns the remainder of the truncating division of this integer by
other
.override 
shiftRightUnsigned(
int n) → Int64 
Unsigned rightshift operator.
override

toBytes(
) → List< int?> 
Returns a bytesequence representation of this integer.
override

toDebugString(
) → String 
toDouble(
) → double 
Returns the double representation of this integer.
override

toHexString(
) → String 
Returns a string representing the value of this integer in hexadecimal
notation; example:
'0xd'
.override 
toInt(
) → int 
Returns the int representation of this integer.
override

toInt32(
) → Int32 
Returns an Int32 containing the low 32 bits of this Int64.
override

toInt64(
) → Int64 
Returns
this
.override 
toRadixString(
int radix) → String 
Returns a string representing the value of this integer in the given radix.
override

toRadixStringUnsigned(
int radix) → String 
toSigned(
int width) → Int64 
Returns the least significant
width
bits of this integer, extending the highest retained bit to the sign. This is the same as truncating the value to fit inwidth
bits using an signed 2s complement representation. The returned value has the same bit value in all positions higher thanwidth
.override 
toString(
) → String 
Returns the value of this Int64 as a decimal String.
override

toStringUnsigned(
) → String 
Returns the digits of
this
when interpreted as an unsigned 64bit value. 
toUnsigned(
int width) → Int64 
Returns the least significant
width
bits of this integer as a nonnegative number (i.e. unsigned representation). The returned value has zeros in all bit positions higher thanwidth
