dstore_n : store double in local variables <n> and <n> + 1 : index :

Description

Pops a double-precision float off of the operand stack and stores it in the local variables <n> and <n> + 1. Both <n> and <n> + 1 must be valid local variable numbers in the current frame.

See the description of dstore for more information on how doubles are stored in local variables.

'dstore_n' is functionally equivalent to 'dstore <n>', although it is typically more efficient and also takes fewer bytes in the bytecode.

Example

dstore_0        ;store double in local variable 0 and 1
dstore_1        ;store double in local variable 1 and 2
dstore_2        ;store double in local variable 2 and 3
dstore_3        ;store double in local variable 3 and 4
