validateDecimalRangeStrict(value, min, max, fieldName): void

Validates decimal number within range (handles NaN, Infinity, type checking)

Centralizes strict decimal range validation for numeric inputs.

Replaces Pattern​

Before (Duplicate across services):​

const num = parseFloat(value);
if (isNaN(num) || num < min || num > max) {
  throw new ValidationError(`${fieldName} must be between ${min} and ${max}`);
}

After (Single call):​

validateDecimalRangeStrict(value, min, max, 'slippageTolerance');

Parameters​

value​

string | number

The value to validate (string or number)

min​

number

Minimum allowed value (inclusive)

max​

number

Maximum allowed value (inclusive)

fieldName​

string

Field name for error messages (e.g., 'slippageTolerance', 'priceImpact')

Returns​

void

Throws​

If value is not a valid number within range, or if NaN/Infinity detected

Examples​

Slippage tolerance validation

import { validateDecimalRangeStrict } from '../utils/validation-patterns';

function swap(slippage: unknown) {
  validateDecimalRangeStrict(slippage, 0, 1, 'slippageTolerance');
  // Validation passed - slippage is a valid decimal between 0 and 1
}

Price impact validation

import { validateDecimalRangeStrict } from '../utils/validation-patterns';

function calculateImpact(impactPercent: unknown) {
  validateDecimalRangeStrict(impactPercent, 0, 100, 'priceImpact');
  // Validation passed - impact is valid percentage between 0 and 100
}
