# Should I use decimal or double?

## Should I use decimal or double?

If numbers must add up correctly or balance, use decimal. This includes any financial storage or calculations, scores, or other numbers that people might do by hand. If the exact value of numbers is not important, use double for speed.

### Should I use decimal or double C#?

Use double for non-integer math where the most precise answer isn’t necessary. Use decimal for non-integer math where precision is needed (e.g. money and currency). Use int by default for any integer-based operations that can use that type, as it will be more performant than short or long .

#### Should I use float or double?

Float and double Double is more precise than float and can store 64 bits, double of the number of bits float can store. Double is more precise and for storing large numbers, we prefer double over float. For example, to store the annual salary of the CEO of a company, double will be a more accurate choice.

Should I use float or decimal?

Float stores an approximate value and decimal stores an exact value. In summary, exact values like money should use decimal, and approximate values like scientific measurements should use float. When multiplying a non integer and dividing by that same number, decimals lose precision while floats do not.

What is the difference between decimal and double?

The main difference between decimal and double data types is that decimals are used to store exact values while doubles, and other binary based floating point types are used to store approximations.

## What is the difference between float double and decimal?

The main difference is Floats and Doubles are binary floating point types and a Decimal will store the value as a floating decimal point type. So Decimals have much higher precision and are usually used within monetary (financial) applications that require a high degree of accuracy.

### What is difference between decimal and double?

The fundamental difference is that the double is a base 2 fraction, whereas a decimal is a base 10 fraction. double stores the number 0.5 as 0.1, 1 as 1.0, 1.25 as 1.01, 1.875 as 1.111, etc. decimal stores 0.1 as 0.1, 0.2 as 0.2, etc.

#### What is the difference between decimal float and double in net?

Decimal, Float and Double Precision is the main difference where float is a single precision (32 bit) floating point data type, double is a double precision (64 bit) floating point data type and decimal is a 128-bit floating point data type.

What is the difference between float decimal and double?

What is the difference between Decimal, Float and double?

The Decimal, Double, and Float variable types are different in the way that they store the values. Precision is the main difference where float is a single precision (32 bit) floating point data type, double is a double precision (64 bit) floating point data type and decimal is a 128-bit floating point data type.

## What’s the difference between float and double precision?

Precision is the main difference (Notice that this is not the single difference) where float is a single precision (32 bit) floating point data type, double is a double precision (64 bit) floating point data type and decimal is a 128-bit floating point data type.

### What’s the difference between decimal and double precision?

Precision is the main difference where float is a single precision (32 bit) floating point data type, double is a double precision (64 bit) floating point data type and decimal is a 128-bit floating point data type.

#### How many bytes does a float and double use?

Float uses 4 bytes to represent value, Double uses 8 bytes to represent value. Example: percentage FLOAT (5,2), same as the type decimal, 5 is total digits and 2 is the decimal places. percentage will store values between -999.99 to 999.99.
