Copy-paste fix pattern
library CB-Math
fn main() {
f64 value = CB-Math.sqrt_or(-5, 0)
println(to_string(value))
}Why it happens
A floating-point operation produced NaN, positive infinity, or negative infinity.
How to fix it
Use fallback helpers for sqrt, division, log, and user-entered numbers.
If the IDE reports a line number, fix that line first, then scan the previous line for an unclosed string, bracket, or block.
