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.
