float

The float module provides float conversion, rounding, and math utilities. It is auto-imported — no import statement needed.

Function Reference

Conversion

Function	Signature	Description
to_string	(Float) -> String	String representation
to_int	(Float) -> Int	Truncate toward zero
from_int	(Int) -> Float	Convert integer to float
parse	(String) -> Result[Float, String]	Parse string to float
to_fixed	(Float, Int) -> String	Format with fixed decimal places

Rounding

Function	Signature	Description
round	(Float) -> Float	Round to nearest integer
floor	(Float) -> Float	Round down
ceil	(Float) -> Float	Round up

Arithmetic

Function	Signature	Description
abs	(Float) -> Float	Absolute value
sqrt	(Float) -> Float	Square root
min	(Float, Float) -> Float	Smaller of two
max	(Float, Float) -> Float	Larger of two
clamp	(Float, Float, Float) -> Float	Clamp to range [lo, hi]
sign	(Float) -> Float	Sign: -1.0, 0.0, or 1.0

Checks

Function	Signature	Description
is_nan	(Float) -> Bool	Check if NaN
is_infinite	(Float) -> Bool	Check if infinite

Examples

float.to_string(3.14)       // => "3.14"
float.to_int(3.9)           // => 3
float.round(3.6)            // => 4.0
float.parse("3.14")         // => ok(3.14)
float.to_fixed(3.14159, 2)  // => "3.14"
float.abs(-2.5)             // => 2.5
float.clamp(15.0, 0.0, 10.0)// => 10.0
