`tokenize("42")` → `[Token('NUMBER', 42), Token('EOF', None)]` ✓  
`tokenize("3.14")` → `[Token('NUMBER', 3.14), Token('EOF', None)]` ✓  
`tokenize(".5")` → `[Token('NUMBER', 0.5), Token('EOF', None)]` ✓  
`tokenize("10.")` → `[Token('NUMBER', 10.0), Token('EOF', None)]` ✓

`tokenize("  12  +  3 ")` → `[NUMBER, PLUS, NUMBER, EOF]` (spaces skipped) ✓  
`tokenize("1 @ 2")` → raises `calc.lexer.LexError: unexpected character '@' at position 2` ✓  
`tokenize("1 a 2")` → raises `LexError` ✓
