INSTALL
(cd /usr/bin; mv dc dc0)
cp /usr/local/share/examples/rc.dc ~/.dcrc
EXAMPLES
`2pi` => `6.28...` // `2pi` equal to `2*pi`
`a=12` => `12` // define a variable `a`
`2(3+a` => `30` // `2(3+a` equal to `2*(3+a)`
`b=2a` => `24` // define a var `b`
`c:=2a` // define a delayed-var `c`
`a=3` => `3` // modify a's value
`b` => `24` // `b` doesn't update according to `a`
`c` => `6` // `c` update according to `a`
`sind[x]=sin[x pi/180]` // define a 1-var function `sind`
`sind[30]` => `0.5`
`int[c x+1,x,1,2]` => `10` // integration
`sum[k,k,1,10]` => `55` // summation
`k` => `1000`
`m` => `1e-3`
`M` => `1e6`
.... // defined in `rc.dc`(auto-load script)
`1/2'k` => `0.005` // `1/2'k` equal to `1/(2*k)`
`0x10` => `16` // hex
`0b1011` => `11` // bin
`ans&0b1100` => `1000b` // AND operation
`?` // Show brief help message
`>aa` // SAVE user var's & fun's in `aa`
`<aa` // LOAD user var's & fun's from `aa`
