Real type

Real/Float type. Equivalent to the 'double' type in C

Direct parent types

Num: A number
Direct subtypes: 2

Constructors

Real(n:Int): Convert Int to Real

Real() Source: stdlib.ngs:190: Get zero
Returns
0.0

Real(s:Str) Source: stdlib.ngs:886

Convert a string to real (floating) number, inefficiently

Returns

Real

Example

Real("1.1")  # 1.1

Methods

*(a:Real, b:Real): Multiplication

+(a:Real, b:Real): Addition

-(a:Real, b:Real): Subtraction

/(a:Real, b:Real): Division

<(a:Real, b:Real): Less-than comparison

<=(a:Real, b:Real): Less-than-or-equal comparison

==(a:Real, b:Real): Compare floating point numbers. Using this operator/function is not recommended.

>(a:Real, b:Real): Greater-than comparison

>=(a:Real, b:Real): Greater-than-or-equal comparison

Arg(x:Real) Source: stdlib.ngs:4910

Convert to string, appropriate for using as argument to external process.

Automatically called by NGS for syntax

$(mycommand $num) # num is Real

ceil(r:Real)

Ceil a number

Example

ceil(1.1)   # 2.0
ceil(-1.1)  # -1.0

floor(r:Real)

Floor a number

Example

floor(1.1)   # 1.0
floor(-1.1)  # -2.0

inspect(r:Real) Source: stdlib.ngs:6007: Inspect Real
Returns
Lines with exactly one line

Int(r:Real): Convert Real (floating) number to Int. Floating part is truncated.
Returns
Int

round(r:Real): Round a number

Str(r:Real): Convert Real to Str

trunc(r:Real): Truncate a number
