What is a Decimal Calculator?

A decimal calculator is an online tool or digital calculator that specializes in performing operations with decimal numbers. It supports basic calculations (like addition and subtraction) and advanced functions (like logarithms and exponents). Decimal calculators are particularly useful in fields that require precise numerical results, such as science, engineering, and finance.

Formula and Operations

Addition

Formula: \[a + b\]

This operation adds two decimal numbers to give the total sum.

Subtraction

Formula: \[a - b\]

Subtraction finds the difference between two decimal numbers.

Multiplication

Formula: \[a \times b\]

Multiplication gives the product of two decimal numbers.

Division

Formula: \[\frac{a}{b}\]

Division splits a decimal number by another, giving a quotient.

Exponent

Formula: \[a^b\]

Exponentiation raises a decimal number (base) to the power of another (exponent).

Root

Formula: \[\sqrt[b]{a}\]

Root finds a number that, when multiplied by itself a given number of times, gives the original decimal.

Logarithm

Formula: \[\log_b(a)\]

Logarithm finds the power to which a base must be raised to obtain a given decimal number.

Explanation of Formulas with Examples

Addition

Calculation: \[5.75 + 3.2\]

Solution: \[8.95\]

Subtraction

Calculation: \[10.5 - 4.3\]

Root

Calculation: \[\sqrt[3]{8.0}\]

Solution: \[2.0\]

Logarithm

Calculation: \[\log_{10}(100)\]

Solution: \[2\]

Units of Measurement

In decimal calculations, units may vary depending on the context, but typically, calculations are performed with unitless values unless otherwise specified, especially in scientific applications.
