- abs
-
Int abs()
Return the absolute value of this integer. If this value is positive then return this, otherwise return the negation.
- amp
-
Bitwise-and of this and b. Shortcut is a&b.
- caret
-
Bitwise-exclusive-or of this and b. Shortcut is a^b.
- compare
-
Compare based on integer value.
- decrement
-
Int decrement()
Decrement by one. Shortcut is --a or a--.
- equals
-
Return true if same integer value.
- fromDigit
-
Int fromDigit(Int radix := def)
Convert a Unicode digit character into a number for the specified radix. Return null if this char is not a valid digit.
Example:
'3'.fromDigit -> 3 'f'.fromDigit(16) -> 15 '%'.fromDigit -> null
- fromStr
-
static Int fromStr(Str s, Int radix := def, Bool checked := def)
Parse a Str into a Int using the specified radix. If invalid format and checked is false return null, otherwise throw ParseErr.
- hash
-
override Int hash()
Return this.
- increment
-
Int increment()
Increment by one. Shortcut is ++a or a++.
- isAlpha
-
Bool isAlpha()
Return if this Unicode char is an ASCII alpha char: isUpper||isLower
- isAlphaNum
-
Bool isAlphaNum()
Return if this Unicode char is an ASCII alpha-numeric char: isAlpha||isDigit
- isDigit
-
Bool isDigit(Int radix := def)
Return if this Unicode char is an digit in the specified radix. A decimal radix of ten returns true for
0
-'9'. A radix of 16 also returns true fora
-'f' andA
-'F'.Example:
'3'.toDigit -> true 3.toDigit -> false 'B'.toDigit(16) -> true
- isEven
-
Bool isEven()
Return if this integer is evenly divisible by two.
- isLower
-
Bool isLower()
Return if this Unicode char is an ASCII lowercase alphabetic char: a-z
- isOdd
-
Bool isOdd()
Return if this integer is not evenly divisible by two.
- isSpace
-
Bool isSpace()
Return if this Unicode char is whitespace: space \t \n \r \f
- isUpper
-
Bool isUpper()
Return if this Unicode char is an ASCII uppercase alphabetic char: A-Z
- localeIsLower
-
Bool localeIsLower()
Return if this Unicode char is a lowercase letter in the current locale. See also localeIsUpper and isLower.
- localeIsUpper
-
Bool localeIsUpper()
Return if this Unicode char is an uppercase letter in the current locale. See also localeIsLower and isUpper.
- localeLower
-
Int localeLower()
If this Unicode char is an uppercase char, then return it as lowercase according to the current locale. Note that Unicode contains some case conversion rules that don't work correctly on a single character, so
Str.localeLower
should be preferred. See also localeUpper and lower. - localeUpper
-
Int localeUpper()
If this Unicode char is a lowercase char, then return it as uppercase according to the current locale. Note that Unicode contains some case conversion rules that don't work correctly on a single character, so
Str.localeLower
should be preferred. See also localeLower and upper. - lower
-
Int lower()
If this Unicode char is an ASCII uppercase char, then return it as lowercase, otherwise return this.
Example:
'A'.lower -> 'a' 'h'.lower -> 'h'
- lshift
-
Bitwise left shift of this by b. Shortcut is a<<b.
-
new make()
Private constructor.
- max
-
Return the larger of this and the specified Int values.
- min
-
Return the smaller of this and the specified Int values.
- minus
-
Subtract b from this. Shortcut is a-b.
- negate
-
Int negate()
Negative of this. Shortcut is -a.
- percent
-
Return remainder of this divided by b. Shortcut is a%b.
- pipe
-
Bitwise-or of this and b. Shortcut is a|b.
- plus
-
Add this with b. Shortcut is a+b.
- random
-
static Int random(Range r := def)
Generate a random number. If range is null then all 2^64 integer values (both negative and positive) are produced with equal probability. If range is non-null, then the result is guaranteed to be inclusive of the range.
Examples:
r := Int.random r := Int.random(0..100)
- rshift
-
Bitwise right shift of this by b. Shortcut is a>>b.
- slash
-
Divide this by b. Shortcut is a/b.
- star
-
Multiply this with b. Shortcut is a*b.
- tilde
-
Int tilde()
Bitwise inverse of this. Shortcut is ~a.
- times
-
Call the specified function to this times passing the current counter.
- toChar
-
Str toChar()
Map as a Unicode code point to a single character Str.
- toDigit
-
Convert this number into a Unicode char
0
-'9'. If radix is is greater than 10, then use a lower case letter. Return null if this number cannot be represented as a single digit character for the specified radix.Example:
3.toDigit -> '3' 15.toDigit(16) -> 'f' 99.toDigit -> null
- toFloat
-
override Float toFloat()
Convert this Int to a Float.
- toHex
-
Str toHex()
Return hexdecimal string representation.
- toInt
-
override Int toInt()
Return this.
- toStr
-
override Str toStr()
Return decimal string representation.
- upper
-
Int upper()
If this Unicode char is an ASCII lowercase char, then return it as uppercase, otherwise return this.
Example:
'a'.upper -> 'A' '4'.upper -> '4'
