Member Function Documentation

equals()

static constexpr bool QJSNumberCoercion::equals ( double lhs, double rhs )

inlinestaticconstexpr

Definition at line 60 of file qjsnumbercoercion.h.

isArrayIndex() [1/3]

static constexpr bool QJSNumberCoercion::isArrayIndex ( double d )

inlinestaticconstexpr

Checks whether d contains a value that can serve as an index into an array. For that, d must be a non-negative value representable as an unsigned 32bit int.

Definition at line 28 of file qjsnumbercoercion.h.

isArrayIndex() [2/3]

static constexpr bool QJSNumberCoercion::isArrayIndex ( qint64 i )

inlinestaticconstexpr

Checks whether i contains a value that can serve as an index into an array. For that, d must be a non-negative value representable as an unsigned 32bit int.

Definition at line 36 of file qjsnumbercoercion.h.

isArrayIndex() [3/3]

static constexpr bool QJSNumberCoercion::isArrayIndex ( quint64 i )

inlinestaticconstexpr

Checks whether i contains a value that can serve as an index into an array. For that, d must be a value representable as an unsigned 32bit int.

toInteger()

static constexpr int QJSNumberCoercion::toInteger ( double d )

inlinestaticconstexpr

Coerces the given d to a 32bit integer by JavaScript rules and returns the result.
