Number¶
Represents a double-precision floating point value. Supports exponents (XeY) and hexadecimal (0xAAAAAAAA) values. NaN is used to denote a invalid number. Infinity, negative infinity and NaN can be created using native number helpers.
Syntax (RegExp)
-?\d+(\.\d+)?
-?\d+(\.\d+)?e(\+|-)?\d+
-?0[Xx][A-Fa-f]+
Example
0
-140
-9.2
100
250.67
10e2
10e-4
0xfff
Properties¶
sign¶
Returns the -1 (less than zero), 0 (zero) or 1 (greater than zero).
Signature
-> : Number
Example
num := -5;
# prints -1
print(num.sign());
isFinite¶
Is the number finite?
Signature
-> : Boolean
Example
num := 5;
# prints true
print(num.isFinite());
isInfinite¶
Is the number infinite?
Signature
-> : Boolean
Example
num := 5;
# prints false
print(num.isInfinite());
isNaN¶
Is the number NaN?
Signature
-> : Boolean
Example
num := 5;
# prints false
print(num.isNaN());
isNegative¶
Is the number negative?
Signature
-> : Boolean
Example
num := 5;
# prints false
print(num.isNegative());
abs¶
Returns the number without sign.
Signature
-> : Number
Example
num := -5;
# prints 5
print(num.abs());
ceil¶
Returns the number rounded towards positive infinity.
Signature
-> : Number
Example
num := 5.1;
# prints 6
print(num.ceil());
round¶
Returns the number rounded towards negative infinity.
Signature
-> : Number
Example
num := 5.5;
# prints 6
print(num.round());
truncate¶
Returns the number discarding fractional digits.
Signature
-> : Number
Example
num := 5.45;
# prints 5
print(num.truncate());
toPrecisionString¶
Returns the number string with specified precision. Precision must satisfy 1 <= precision <= 21.
Signature
-> Number digits : String
Example
num := 5.2512;
# prints "5.25"
print(num.toPrecisionString(3));
toRadixString¶
Returns the radix equivalent of the number.
Signature
-> Number radix : String
Example
num := 5;
# prints 101
print(num.toRadixString(2));
