// The following fixes the inconsisties in the JS % (modulus) operator when used on fractional numbers

// Example 1
// Multiply both sides of operand by 10000
let remainder = (100 * 10000) % (0.33 * 10000);

// Example 2
// Divide the numbers, then apply the modulus of result by 1
remainder = (100 / 0.33) % 1;
