format -- format a string or a real number

Description

Usage:

format(s)
Inputs:
- s
Outputs:
- a string obtained from s by inserting escape sequences, thereby preparing it for printing in a form suitable for reading in again

i1 : s = "a\"b\"c"

o1 = a"b"c

i2 : t = format s

o2 = "a\"b\"c"

i3 : u = value t

o3 = a"b"c

i4 : u == s

o4 = true

Usage:

format(s,k,l,t,e,x)
Inputs:
- s, an integer, the maximum number of significant decimal digits (default: printingPrecision). The special value 0 imposes no limit.
- k, an integer, how far to the right of the decimal point to go, at most (default: printingAccuracy). The special value -1 imposes no limit.
- l, an integer, maximum number of leading zeroes (default: printingLeadLimit)
- t, an integer, maximum number of trailing zeroes (default: printingTrailLimit)
- e, a string, the separator between the mantissa and the exponent (default: printingSeparator)
- x, a real number, the number to be converted to a string
Outputs:
- a string, the decimal representation of the number x, prepared according to the parameters above

i5 : format(10,1/3000.)

o5 = .0003333333333

i6 : format(10,6,1/3000.)

o6 = .000333

i7 : format(10,6,2,1/3000.)

o7 = 3.33e-4

i8 : format(10,300000.)

o8 = 300000

i9 : format(10,-1,10,5,300000.)

o9 = 300000

i10 : format(10,-1,10,4,300000.)

o10 = 3e5

i11 : format(10,-1,10,4,"E",300000.)

o11 = 3E5
