Blorp by Example

Numbers and Safe Arithmetic

Blorp keeps numeric behavior explicit: default arithmetic is infallible, and checked helpers model failure.

Int

Int is the default whole-number type.

int.brp

count: Int = 42

Float

Float is the default floating-point type.

float.brp

ratio: Float = 0.75

Sized Numbers

Use Int8, UInt8, Int32, Float32, and related types when size is part of the contract.

sized.brp

byte: UInt8 = to_uint8(255)
small: Int32 = to_int32(42)

Wrapping Defaults

Integer overflow wraps, and integer division or modulo by zero returns 0 by default.

wrapping.brp

wrapped: UInt8 = to_uint8(255) + to_uint8(1)

Checked Helpers

Use helpers such as divide_checked, add_checked, or mod_checked when a failure value matters.

checked.brp

import:
    int: divide_checked

match divide_checked(10, 0):
    Ok(n): print(n.to_string())
    Err(_): print("cannot divide")

Example

numbers.brp

import:
	int: divide_checked


func main(args: List[String]) -> Void:
	byte: UInt8 = to_uint8(255)
	flags: UInt8 = bit_or(to_uint8(1), shift_left(to_uint8(1), 3))

	match divide_checked(10, 0):
		Ok(value): print(value.to_string())
		Err(_): print("cannot divide")

	print(byte.to_string())
	print(flags.to_string())
