Import

import 'package:big_dec/big_dec.dart';

Addition

BigDec bigDec1 = BigDec.fromString("1.5");
BigDec bigDec2 = BigDec.fromString("1.5");
BigDec result = bigDec1.add(bigDec2);
print(result.toStringAsFixed(0));

Subtraction

BigDec bigDec1 = BigDec.fromString("3.36");
BigDec bigDec2 = BigDec.fromString("1.5");
BigDec result = bigDec1.subtract(bigDec2);
print(result.toStringAsFixed(4));

Multiplication

BigDec bigDec1 = BigDec.fromString("1.5");
BigDec bigDec2 = BigDec.fromString("3");
BigDec result = bigDec1.multiply(bigDec2);
print(result.toStringAsFixed(4));

Division

BigDec bigDec1 = BigDec.fromString("1");
bigDec1.setDecimalPrecision(100);
BigDec bigDec2 = BigDec.fromString("3");
BigDec result = bigDec1.divide(bigDec2);
print(result.toStringAsFixed(BigDec.getMaxAmountOfDecimalPlaces()));

Decimal Precision

Set a new decimal precision. The rest of the operations inherit the decimal precision from the first BigDec.

BigDec bigDec1 = BigDec.fromString("1");
bigDec1.setDecimalPrecision(100);

Round

BigDec bigDec1 = BigDec.fromString("1.5");
BigDec result = bigDec1.round();

Floor

BigDec bigDec1 = BigDec.fromString("1.5");
BigDec result = bigDec1.floor();

Ceil

BigDec bigDec1 = BigDec.fromString("1.5");
BigDec result = bigDec1.ceil();

Power

BigDec bigDec1 = BigDec.fromString("25");
BigDec result = bigDec1.pow(BigInt.from(4));
print(result.toString());

Square root

BigDec bigDec1 = BigDec.fromString("25");
BigDec result = bigDec1.sqrt();
print(result.toString());

Absolute value

BigDec bigDec1 = BigDec.fromString("-25");
BigDec result = bigDec1.abs();
print(result.toString());

GPU Acceleration

Initialize the GPU before using hardware-accelerated methods. These methods utilize WGSL compute shaders for high-throughput calculations.

Initialize GPU

await BigDec.initGPU();

GPU Multiplication

BigDec bigDec1 = BigDec.fromString("1234.56");
BigDec bigDec2 = BigDec.fromString("78.9");
BigDec result = await bigDec1.gpuMultiply(bigDec2);
print(result.toString());

GPU Batch Multiplication

Process multiple calculations simultaneously on the GPU for maximum performance.

List<BigDec> listA = [BigDec.fromString("10"), BigDec.fromString("20")];
List<BigDec> listB = [BigDec.fromString("5"), BigDec.fromString("2")];
List<BigDec> results = await BigDec.gpuBatchMultiply(listA, listB);

Other GPU Methods

The following methods are also available for GPU-based calculations:

BigDec resultAdd = await bigDec1.gpuAdd(bigDec2);
BigDec resultSub = await bigDec1.gpuSubtract(bigDec2);
BigDec resultDiv = await bigDec1.gpuDivide(bigDec2);
BigDec resultSqrt = await bigDec1.gpuSqrt();
BigDec resultPow = await bigDec1.gpuPow(BigInt.from(3));
