Name

Int Function

Class

Microsoft.VisualBasic.Conversion

Syntax

Int(number)
number (required; any valid numeric data type)

The number to be processed

Return Value

Returns a value of the data type passed to it

Description

Returns the integer portion of a number

Rules at a Glance

  • The fractional part of number is removed, and the resulting integer value is returned. Int does not round number to the nearest whole number. For example, Int(100.9) returns 100.

  • If number is negative, Int returns the first negative integer less than or equal to number. For example, Int(-10.1) returns -11.

Programming Tips and Gotchas

  • Int and Fix work identically with positive numbers. However, for negative numbers, Fix returns the first negative integer greater than number, while Int returns the first negative integer less than number. For example, Fix(-10. 1) returns -10, while Int(-10.1) returns -11.

  • Don’t confuse the Int function with CInt. CInt casts the number passed to it as an Integer data type, whereas Int returns the same data type that was passed to it.
