VBC00042 — Numeric literal overflow

Severity: Error · Family: VBC (parser / concrete syntax tree) · Source metadata: VBSyntaxErrorInfo

A numeric literal was written whose value does not fit the type the literal resolves to. The type is fixed by the literal's own form (a type-declaration suffix, the presence of a decimal point or exponent, or a radix prefix) before any context is considered. The overflow is therefore a property of the literal alone, and is caught while the syntax tree is built.

See RD-VBAL §3.2.0 Literal Expressions and MS-VBAL §3.3.2 Number Tokens.

The verbose detail names the literal and the type it overflowed.

How it is raised

Situation	Example	Resolution
A type-declaration suffix pins the literal to a type it cannot fit.	`99999%`: `%` is `Integer` (max 32767)	Drop the suffix, use a wider one (`99999&`), or reduce the value.
An unsuffixed integer literal exceeds `Long`.	`3000000000`	Add `@` (`Currency`) or `#` (`Double`), or write it as a narrower value.
An unsuffixed floating-point literal (decimal point or exponent) overflows to infinity.	`1E400`	Reduce the magnitude; the largest `Double` is about `1.8E308`.
A hexadecimal or octal literal without a suffix exceeds 32 bits.	`&HFFFFFFFFF`	Add `&` to force `Long` semantics, or use fewer digits.

Notes

This is a syntax error, not a runtime one: the literal is rejected before evaluation, regardless of where it appears.

A value that fits its literal type but not its assignment target is a separate, later concern (a let-coercion / type-mismatch diagnostic), not VBC00042.
