float() - Pine Script Function

float()

Overview

float() casts a value to the floating-point type. It is useful when you receive generic inputs (strings, ints, na) and need a numeric result for calculations.

Syntax

float(x) → const float

Parameters

Name	Type	Description
x	const int/float/bool/string	Value to convert to float.

Returns

const float — result of the cast (na if conversion is not possible).

Remarks

• na converts to na.
• true → 1.0, false → 0.0.
• Strings must be numeric (e.g., "12.5"); otherwise, the result is na.

Example

//@version=5
indicator("float() example", overlay=false)

strInput = input.string("12.5", "String input")
boolInput = input.bool(true, "Bool input")

floatFromString = float(strInput)
floatFromBool   = float(boolInput)

plot(floatFromString, "Float from string", color=color.blue)
plot(floatFromBool, "Float from bool", color=color.orange)
