Floor Example Syntax C-Sharp ASP.NET | C# Floor | Source Code
Summary: – Illustrates using Floor with Source Code Syntax Example in C-Sharp ASP.NET.
Purpose:
takes a decimal or double number and returns a value
that represents the next equal or lower whole number.
Although the result is a whole number, it is returned as a
the same data type that was passed in. Math.Ceiling is different
in that it rounds up to the next whole number that is equal
or greater than the number that is given.
Syntax:
Floor(decimalnumber)
Floor(decimalnumber)
Parameters | Description | decimalnumber | decimal number |
---|
Result Data Type | Description | decimal | closest whole number equal or lower |
---|
Syntax2:
Floor(doublenumber)
Floor(doublenumber)
Parameters | Description | doublenumber | double precision floating point number |
---|
Result Data Type | Description | double precision floating point number | closest whole number equal or lower |
---|
Quick Example | Floor(1.32) // Returns 1 |
