ErrorInfo

Catches a run-time error and converts it to an error information structure.

Syntax

• ErrorInfo(expr)

  • expr is an expression

Description

If expr raises an error, then ExprInfo(expr) catches this error and returns an error information (ErrorInfo) structure containing information about the error; execution then resumes normally. If expr doesn’t raise an error, ErrorInfo returns null.

Examples

ErrorInfo(∫(sin(t + √(1/t + 1)), t, 0, π))
