CSng Function


CSng Function

Syntax

     Dim result As Single = CSng(expression) 


expression (required; Numeric or String)

Any expression in the valid range of the Single data type.

Description

The CSng function converts expression to the Single data type.

Usage at a Glance

  • An expression that evaluates outside the valid range of the target data type results in a runtime error. Nonnumeric expressions also generate an error.

  • In most cases, the numeric conversion functions are a better choice than the Val function when converting a string, as the conversion functions take into account the system's regional settings. However, Val converts empty strings to zero without error.

  • Use IsNumeric to test whether expression evaluates to a number.

  • This function does not support named arguments.

Example

     Dim targetNumber As Single     If IsNumeric(stringNumber) Then        targetNumber = CSng(stringNumber)     End If
