rangeint 1.0.1

A clamped integer type with range-aware arithmetic, callbacks, and lerp utilities.

RangeInt

A clamped numeric type for Python. Values are automatically kept within a [min, max] range — all arithmetic, assignment, and mutations clamp silently. Built for game dev, UI sliders, stat systems, animation, or anywhere you want a number that stays in bounds.

from rangeint import RangeInt

hp = RangeInt(100, 0, 100)
hp -= 999
print(hp)  # 0  — never goes below min

Install

pip install rangeint

Quick Start

from rangeint import RangeInt

volume = RangeInt(50, 0, 100)

volume += 80     # → 100  (clamped at max)
volume -= 200    # → 0    (clamped at min)

print(int(volume))    # 0
print(float(volume))  # 0.0
print(volume == 0)    # True

API

Constructor

RangeInt(value, min_val, max_val)

Raises ValueError if min_val == max_val.

Properties

Property	Description
.value	Current value (clamped on set)
.min	Lower bound
.max	Upper bound

Methods

relative() -> float

Returns the value's position as a float between 0.0 and 1.0.

RangeInt(75, 0, 100).relative()  # 0.75

lerp_to(percentage) -> float

Sets the value to a fractional position between min and max.

r = RangeInt(0, 0, 200)
r.lerp_to(0.5)   # 100.0

nudge_percentage(amt) -> int

Shifts the value by a fraction of the total range.

r = RangeInt(50, 0, 100)
r.nudge_percentage(0.1)   # 60

set_range(min_val, max_val) -> RangeInt

Updates the bounds and re-clamps the current value. Chainable.

r = RangeInt(80, 0, 100)
r.set_range(0, 50)   # value clamped to 50

edge_check(val_check) -> bool

Returns True if the value is at "min" or "max".

RangeInt(0, 0, 100).edge_check("min")   # True
RangeInt(0, 0, 100).edge_check("max")   # False

is_between(low, high) -> bool

Returns True if the relative position falls within [low, high].

RangeInt(50, 0, 100).is_between(0.25, 0.75)  # True

on_percentage(percentage, directional, through)

Register a function to fire whenever the value crosses a relative threshold if through is set to False it will only fire if it is exact. if through is set to True it will fire if it passes through. Directional controls if it fires when its coming up 30 - 70 or down 70 - 30.

health = RangeInt(0, 0, 100)
def low_health():
  print("Low Health: {health.value()}HP remaining")
health.on_percentage(0.5, low_health, directional="down", through=True)
health += 70
health -= 40 # Low Health: 30HP remaining

Note: Only one function can be assigned to each percentage level
